Who can beat Hulk in a room filled with Laughing Gas?

No Cosmics 
No Magic Users 
No Magic Entities. 
No Getting Angry for Hulk. 
Hulk is constantly laughing and in a good mood.

Hundreds of people.

So.. the point of the OP is that the Hulk is constantly laughing and in a good mood and can't keep getting stronger because he's happy?

Well in that case I'm gonna say the Idol a' Millions, the Everylovin' Blue Eyed Thing could take him!

(Ok yes I know Laughing Gas doesn't actually work that way, but hell. this is Comics and how many chances am I gonna get to call a Hulk/Thing fight for Ben?)

steel

Hulk in a good mood = Bruce Banner

And since it's laughing gas, it makes me think that the Joker has him like that, and even Joker could take Bruce Banner while he's laughing and in a good mood.
