Given two girls, between whom to choose,
Pick the slut; she has nothing to lose.
She’ll do things nice girls don’t,
There are few things she won’t.
Sluts are nice, and so easy to use!

Gert

There’s a girl in the village called Gert,
Who goes knickerless under her skirt:
She’ll be yours for the night
If you play your cards right,
But you have to pull out when you squirt.
