Billy Crystal Billy Crystal

This week, two dearly departed comedians were honored by the TV industry at large: Billy Crystal paid tribute to his friend Robin Williams at the Emmy Awards, and former Saturday Night Live cast member Phil Hartman finally received a star on the Hollywood Walk of Fame (as well as an entire day dedicated to him). Elsewhere, Jeff Bridges — or was it The Dude? — stopped by The Colbert Report, a new trailer for Gone Girl debuted, and a pair of elephants rocked out to violin music. Check out those clips and more in our weekly roundup of the best online videos:

Emmy Photos: Hits and misses on the red carpet

Robin Williams Emmys tribute: Seth Meyers may have brought the laughs at the 66th Primetime Emmy Awards Monday, but Billy Crystal had everyone reaching for a tissue with his heartfelt homage to Robin Williams. Make sure you've got some Kleenex handy, then check out the tearjerker:

Twitch: Amazon announced this week that it would pay more than $1 billion to purchase Twitch, a website that allows people to watch other people play video games. No, really. The concept may sound like a head-scratcher, but at its peak viewing times, the size of Twitch's audience rivals that of many cable networks.

Phil Hartman Day: On Tuesday, which was officially dubbed Phil Hartman Day in Hollywood, comedian Phil Hartman posthumously received a star on the Hollywood Walk of Fame. During the ceremony, Hartman's former SNL colleagues Kevin Nealon and Jon Lovitz, along with other friends and family members, paid tribute to the NewsRadio star, who was killed by his wife Brynn in 1998. Here's a full replay of the ceremony:

Jeff Bridges on Colbert: A couple of weeks ago, Stephen Colbert (or "Col-bort," if you're Gwen Stefani) taped an introduction to the post-Emmys episode of The Colbert Report. And it begs the question: Was Bridges in character as The Dude from The Big Lebowski at the time, or is this just his natural demeanor? Or a little bit of both? We may never know.

Always Sunny "G--damn It!" supercut: Here's a supercut of every "G--damn it!" from It's Always Sunny in Philadelphia, in chronological order. Because why not?

New Gone Girl trailer: The most revealing Gone Girl trailer yet debuted during the Emmy Awards on Monday night, offering a deeper look into the twisted marriage of Nick (Ben Affleck) and Amy (Rosamund Pike), as well as a glimpse at Neil Patrick Harris' Desi. The movie hits theaters on October 3.

Dancing elephants: Who said animals don't have discerning tastes? Meet Kelly and Viola, a pair of elephants in their mid-40s who have lived together for most of their lives. When violinist Eleanor Bartsch decided to practice a Bach concerto outside their pen at the Circus World Museum in Baraboo, Wisconsin, she received a very enthusiastic response.
