This was some time ago at an old job, a group of ppl standing around and we were talking about working out, being healthy etc... this one fella an older man badly out of shape is looking at me, you know the typical jealous stare and he does it for quite a while before he finally comes up with something. Then he says to me "you know all that muscle looks good now, but when you'll get older it will turn to fat"
so i look at him and say "wow you must have been really muscular when you were young!"
