An old couple who hadn't celebrated Halloween in a long time decided to
dress up and go out. The old woman went into her bedroom, stripped
naked and tied a lemon between her legs.

When she came out, the old man cried, "You can't go out like that!"

She said, "I can go anyway I like and so can you."

Whereupon he retired to the bedroom and came out stark raving naked
with a potato tied to his tallywhacker.

The old woman says, you're going out like that?" and he replies, "Yep,
if you can go as a sour-puss, I can go as a dick-tator."
