A couple of days ago, I was working out at a gym that I'm a member of.  Obviously I see plenty of steroid-abusing loud-mouthed meatheads here, but I can usually ignore them because I'm listening to my iPod.  But on this particular day, a guy paused during his workout, took his shirt off, and started posing in front of a mirror.  I was very close to bursting out in laughter but had to restrain myself because 1) the guy could easily kick my ass if he wanted to and 2) I think it would hurt his feelings because he took it so seriously.  Has anyone else had a memorable experience with a meathead?
