the week in viral videos

The Internet was filled to the brim with viral videos this week, some of which featured amazing ads, crazy crashes and, of course, animals. Our favorite video of the week has to go to a rather, um, unusual race bike crash. Bike crashes are usually good for a laugh, but this crash had us howling about 30 seconds into the video...

Over the last seven days, the Internet gave us a diverse group of viral videos - a refreshing change of pace after all of the Osama bin Laden-related videos from last week. We saw the return of Charlie Sheen, a dead squirrel, a human bicycle, an amazing tennis shot, some incredible street dancing and more.

It was yet another great week for viral Internet videos, and we've compiled the 10 best that had everyone talking. Among our favorites: Hilarious parodies ('When Harry Met Sally 2,' starring Billy Crystal and Helen Mirren), on-air news pranks and a New York-based hot dog that costs, yep, $69. Watch them all below.
