Shrimp On A Treadmill (video)
According to its page on Youtube, the following video featuring a shrimp running on a treadmill is a bit old. Luckily, the included WTF value is still quite intact, at least for someone like me who doesn’t have a career in crustacean athletics. (Flash video from youtube.com embedded below)
There’s also a version with the Benny Hill theme.
