In the Stan Lee Hulk episode a few years back, before Bart comes up with Angry Dad, he says, "I just need one classic character." He sees a bat in the house. "Batman! Ah, it's been done." (sees a green lantern hanging in the house). "Green Lantern! Nah."
Also, the nerdy kid with the glasses is buying a Batman figure at the comic book store. Stan Lee proceeds to sell him a Thing figure instead and crunches the kid's batmobile because the figure's so big.
"Wouldn't you rather have this Thing figure instead?"
"But only Batman fits in my batmobile."
"That's not true, he's fitting right now!"
"Ahhhh! You broke my batmobile!"
Or something to that degree.
