At my Japanese gym there is a guy with the biggest upper body to lower body discrepancy I have yet to see. His name is Kenji and he says "fuck" a lot. I think it's the only English word he knows. Pretty much after every set he'll simply say "fuck" and put his weights back.
He's not IFBB huge, but his upper body would probably get a 7.5 or an 8 if he posted it in RMP.
His legs...you'd see bigger legs on an 80 year old shuffleboard player in Florida. Not quite, but close. There was such a difference that I wondered if he had had a motorcycle accident and was re-learning to walk, or peroneal nerve damage, or polio, or SOMETHING.....but nope, his friends tell me that he wants to keep his legs small because it's fashionable (skinny jeans?)
I'm going to try and snap a picture the next time I'm in...
