1 of 20Mr. Feeny (William Daniels), Boy Meets World
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.
