That’s Paul Reubens (aka Pee Wee Herman) as The Spleen in the excellent movie Mystery Men.
Spoiler quotes:
The Spleen: Why are you guys always dissing me? It hurts my feelings. I’m a superhero too. I have powers.
Invisible Boy: Really? Like what?
The Spleen: So glad you asked. Excuse me. Excuse me. Excuse me. Well, it all started when I was just 13 years of age. One day, while walking with some friends, I accidentally cut the cheese. Well, in my adolescent awkwardness, I blamed it on an old gypsy woman who happened to be passing by. BIG MISTAKE! The gypsy woman placed a curse upon my head. Because I smelled it, she decreed I would forevermore BE HE WHO DEALT IT!
