Goblin: How you eat the snickers bars you got for Halloween.
or how about:
Frankenstein: Hot dog and a mug of beer.
Invisible Man: What a guy becomes when there's housework to be done. Also, see "Mr. Hyde."
Pumpkin Patch: What a pumpkin wears when trying to quit smoking.
"Well, that's nothing compared to the fury of a woman who has been cheated out of tricks or treats."
It's the Great Pumpkin, Charlie Brown...Linus
