To call Mr. Feeny just a neighbor would be an insult to the man. The omniscient George Feeny was much more than just the old guy next door: He served as teacher, principal, college professor and mentor to Cory, Shawn, Eric and Topanga as they grew up right before his eyes. Sure, it's not easy living next to your principal/teacher, but you can't be vexed by anyone who cared enough to follow you through college. We're just surprised he didn't follow the gang when they moved to New York.

No one could better dole out to the Tim "The Toolman" Taylor than good ol' Wilson. Whether the issue was big or small, Wilson always knew just what to say to solve the problem — all while managing to strategically cover-up a good portion of his face.

If a good neighbor is defined as somebody who eats your food, watches your TV and loses your stuff, then Cosmo Kramer is your man. Between the smoking clubs and the neon Kenny Rogers' Roaster sign, Kramer was truthfully a nightmare neighbor. But he always knew how to make an entrance.

While Marcy was Peggy's BFF, she and Al were the definition of arch rivals. Her first husband Steve was a bit condescending to start, but eventually grew to like the Bundys. Her second hubby Jefferson — a male version of Peggy — was Al's close pal and an active member of his NO MA'AM group.

Looking back, the Winslows were just mean, weren't they? Urkel may have been the most exaggerated of nerds — clumsy, permanently bent knees and elbows, suspenders, flood pants, snorting — but he suffered such abuse from every member of the Winslow family. Then again, no one but Urkel got this awesome dance.

Despite the annoying okely dokelys and hi-diddly-hos, deep down we believe Homer and the Simpson clan did appreciate their well-meaning neighborino — no matter how much abuse they subjected him and his family to.

The poster child for annoying and (usually) unwelcome teen neighbors, Kimmy was a thorn in every Tanner family member's side except D.J.'s. They all get extra cool points though for tolerating the Gibb's stinky feet all those years. No wonder Danny was a neat freak.

She was the girl next door, and Kevin was her eager suitor. In six seasons spanning the late '60s and early '70s, we never tired of Kevin and Winnie's on-again, off-again romance. When it was revealed in the series finale that their friendship had lasted through the years — they wrote each other letters every week! Awww — saying goodbye to the show hurt a little less.

He’s the original oleaginous two-face — so much so that for years his name has been synonymous with the archetype of weaselly creeps. He would compliment Mrs. Cleaver in the most treacly way, then in the next minute show his conniving, wiseacre side to his friends and the Beav.

Those silk zebra pajamas. The nights at The Regal Beagle. Larry wasn't just Jack's sleazy best friend, he was our sleazy best friend. The kind that leaves you in the lurch, but you welcome back with open arms because even getting in trouble together is time well spent. Come and knock on our door, indeed.

Fred and Ethel Mertz (William Frawley and Vivian Vance), I Love Lucy Ethel served as a partner in crime, often reluctantly, for Lucy’s goofy antics, while Fred specialized in being befuddled and curmudgeonly. Ethel, though, would confide some of Lucy’s plans to Fred, who, in turn, would alert Ricky. Vance won the first supporting-actress Emmy (in 1954) for her performance.

Monica, Rachel, Phoebe, Joey, Chandler and Ross gave new meaning to "friends and neighbors" and singlehandedly encouraged twentysomethings to move into an apartment building with their buddies. Just make sure you know enough useless trivia about your pals (and their jobs) before you engage in a high-stakes apartment-swapping bet with them.

The couple were the animated equivalent of the Nortons in The Honeymooners — just as Fred and Wilma were avatars for Ralph and Alice Kramden. And the quartet’s dynamic was roughly the same. Barney was originally voiced by the legendary Mel Blanc.

Rhoda Morgenstern (Valerie Harper), The Mary Tyler Moore Show A New York City transplant, she quickly became Mary Richards’ best friend in Minneapolis after moving into the apartment downstairs — two trailblazing single career women. Harper won four Emmys for her performance in the role — one of them for her spin-off, in which she moved back to New York and got married.

"Won't you be my neighbor?" That's how Mr. Rogers greeted everyone who visited his TV neighborhood each day. Unlike many on this list, Mr. Rogers was a giver, not a taker. Every day, he offered up a little bit of education and a fun adventure in the Neighborhood of Make-Believe. They were all beautiful days, indeed.

Ellie and Andy Torres (Christa Miller and Ian Gomez), Cougar Town Ellie and Andy seem like horrible people, as they’ve gone as far as to pretend that their baby died to get free tacos from their neighbor. They make up for it by being the type of neighbors who are there to console Jules during break-ups, take her side on all arguments and even her when she stopped drinking wine. That’s what friends are for.

Marie and Frank Barone (Doris Roberts and Peter Boyle), Everybody Loves Raymond What's worse than having neighbors who drop in unannounced all the time? Parents who drop in unannounced all the time. In Ray and Debra's case, Marie and Frank were both. Whether Frank was watching the game in Ray's recliner or Marie was judging Debra's housekeeping abilities, they were always visiting. It probably would have made more sense for the elder Barones to just move into the basement.

Ed and Trixie Norton(Art Carney and Joyce Randolph), The Honeymooners Ralph Kramden’s “pal o’ mine” was a quirky, good-natured enabler for many of Ralph’s harebrained schemes. But he also could frustrate his rotund buddy and cut him down to size, sending him into paroxysms of fulminating fury. His wife was Alice Kramden’s faithful best friend.

Yes it looks like suburban paradise but sometimes Fairview seems like the worst place to live. Despite suicides, grocery store shootouts, airplane crashes and tornados, the ladies of Wisteria Lane have always been able to lean on each other. Plus, these women are so nosy you don’t even have to wait to tell them your deep dark secret — chances are they’ve already been gossiping it about for weeks.

A modern-day Eddie Haskell, Boner — easily the best inappropriate name on a family sitcom — was a wise-cracking, smooth-talking sycophant who always had Mike's back when they got caught in some mischievous scheme. But he changed everyone's perception of him by joining the Marines midway through the series. We wonder if he still went by "Boner" there.

An airline navigator, he lived across the hall from the Hartleys and had a propensity to barge in on them — particularly at mealtime. The guileless guy was hard not to feed.
