I been reading this comic ever since Scott Adams linked to it from the dilbert site (which I've been reading ever since I became a huge nerd or something), I almost posted this once before but now I can't resist... I KNOW the author has to be a regular member on at least a few of the fitness forums. Imagine the various 'things I hate at the gym' rant threads... as a comic.
Unfit comic

BTW, there is a 30 day archive so if ya like that one you should go back as far as you can and check out more, some of the earlier strips were kinda drab but they pick up pretty quick (oh yeah... and look for the bob character... Is it pure chance that the character named bob sounds incredibly like the bob described in the first post of the classic IM thread...What seperated US from THEM ).
