I'd actually have to go with Norris... He's kinda; a health freak, so I doubt he drinks to often. Hogan and Mr T are built, so body weight alone... Stark is a f'n drunk anyway, so his tolerance is high, Superman is an alien, and SLJ is just a superfreak.
And I'm pretty sure I can drink you under the table, so...
You are the weak link.
