Humour

These are some of my favourite jokes. They're crude, but brilliantly effective:

2 nuns are in a bath. One of them says "Where's the soap". The other says "yes it does doesn't it"
12 Poles were raping a German girl when she cried out "Nein, nein". So 3 of them left.
How do you make you wife scream during sex? Call her and tell her.
