Shit I wear camo shorts all the time. I got like 6 pair of camo cargos, it must be a fat powerlifter thing. Hell I got a pair on right now 
You got me beat, I only have two pair of cameo shorts. Mine are from Old Navy. They're cheap, fit comfortably and look halfway decent, IMO. Sometimes, I leave them on when I work out, they are that comfortable. Also, you can pretty much wear them with anything. To avoid looking too military, I often wear a black T-shirt and sandals with them. -Big fashion statement! LOL!
