Security Guard: So which one is it?
Bruce Banner: Sorry?
SG: Are you the big guy that gets all little? Or the little guy that sometimes blows up large?
BB: You know, I’m not even sure.
SG: You got somewhere to go?
BB: Stark Tower. I … no … yes.
SG: I’d expect some confusion of the mind, since your body is kind of all over the place. But it has to be one or the other.
BB: I know where I can do the most good, but it’s where I can do the most harm. 
SG: Well it’s no different than anybody else.
