The Ultimate Dancing Baby is that lovable little dude that can do all sorts of stuff besides dance.  Here's an animated gif that show him getting medieval on yo ass:

There are lots of things he can do besides karate.  He can do all sorts of tricks, flips on a trampaline, he can dance to a ton of music, and he's even been assimilated by the Borg.  The best one is probably the one where he's drinking, smoking, peeing, and drunkenly fumbling around his own piss.  Click here to see what it's all about.

And, in case you're wondering, this is the biggest attraction to this site.  It gets about 100 hits a day.
