"Wow, you got small!"
"What happened to you!"
"You look so much bigger in magazines!"
"I guess it really was the steroids, huh?"
"Why don't you lift weights anymore?"
"Wow, my husband/friend/dude at my gym is way bigger than you."
"Where did your veins all go?"
"How come your arms are big but everything else is small?"
"How can you do a comeback if you lost all your muscle?"
I bet the retired pros get very tired of questions & comments like this at their booths all day long. Nobody comes up to Joe Montana signing autographs and says "My son can throw a ball farther than you can today". Yet when your entire image is "I'm big" and suddenly you're not, I can see how pros dislike these kinda comments and stay big when it's a bad idea, health-wise".
