Sad Joke that just came to mind:
A wife tells her husband about a dream she had that night. There was a cave full of tables, like a farmer market almost, all these people selling their wares.
What were they selling? the husband asks.
Well, they were selling dicks, all shapes and sizes. Big ones, small ones, every kind you could imagine.
Oh? Where would mine have fit in?
Oh, well, they couldn't even give YOURS away it was so small!
The husband didn't find this overly amusing, and so plotted his revenge. The next morning he woke and told his wife about a dream he had.
I was in a cave and there were people there selling things.
What kinds of things?
Vaginas, if you really must know. Tight ones, loose ones, deep ones, shallow ones, all sizes and fits.
Really? Well then, where do you think mine would've fit in?
Oh, yours was the cave!
