I like the third one... except for the guy... just what is he doing? he looks like he's falling over or something... if he was doing something cooler I'd vote for number 3
The first two are kinda goofy (which may be your preference), third looks ok, though the falling man's a bit lame. you may want to keep looking. Sebi's got the best I've seen on this site, made me laugh the first time I saw it (hits a little too close to home).
