Some of the people around here who've told people they don't use gear just makes me shake my head. Not that it's really THAT big of a deal, it just gives everyone who lifts regularly and passionately a bad name.
I used to have a customer at my old job who claimed to shoulder press 455 for 4 before he had a car wreck that caused brain damage. He also claimed he ran a 4.3 40 at 240 and that he could squat 800 pounds for reps...
The most irritated I've probably ever been with someone "telling lies" was this pink skinned, 160 pound soaking wet idiot at the Rush here in Knoxville who said, with his girlfriend there, "I'd look like that too if I took as many drugs as he probably does." He didn't think I could hear him because I had my headphones on. I asked him why he thought I did drugs. His response, "You can't look like that without drugs. Everyone here knows that." I told him to try working his ass off and eating right sometime.
