IIRC, the Marvel Ultimates version of the Hulk went on a rampage in NYC, and was naked the whole time. I could be wrong, though I remember the Hulk was chasing after Betty at the time and making lewd remarks at her.
And I definitely remember that he was stopped when the Ultimates version of the Wasp took off her top and flashed her “assets” at him. :eek: 
OK I gotta go read the Marvel Ultimates more…
Silly people, he always wears the same pants, because they were gamma-irradiated at the same time he was, and they therefore got the power to stretch as he grows and shrink as he shrinks!
Sheesh. Now you’re going to wonder why Superman’s cape and glasses are indestructable, I’ll bet… (and yes, I know that’s pre-Crisis)

Actually, he was wearing pants that he took off some fat guy he killed in his rampage.
Well, that isn’t what FINALLY stopped him, but it DID stop him for a bit…
