"Are you planning to open a bike shop?"
"Do you ride all of these?"
"Hey, do you think I'd fit on this one?" (Usually coming from my 6' 8" 370 pound a$$ of a brother-in-law, pretending he's going to straddle my Freschi. Needless to say, I'm usually clenching a wrench with white knuckles every time he comes close.)
When fellow forum-ites visit, we usually just exchange a few knowing nods at each others stuff and talk about the ones that got away, or that we should've kept.
