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."
