Hermann Melville's always hilarious Moby Dick contains a special treat for anyone who manages to make it past the first hundred and four chapters without going mental.

A description of a successful whaling ship in chapter 105 ends: "…indeed everything was filled with sperm, except the captain's pantaloons pockets, and those he reserved to thrust his hands into, in self- complacent testimony of his entire satisfaction."

And if you don't believe me, look here.

I think you mean;

I fucked your Mum
I opened up her legs and made her come
She was outstanding
Especially on the landing.

Then move onto the father, remembering that it's not gay to fuck another boy's father;

I fucked your Dad
I fucked him, sucked him, played with his gonads
I felt his power
When we were in the shower.

(Let me try! Cough - here we go...

I snogged your gran,
I mopped up her womb juices with a naan.
I fisted said womb
In her filthy bedroom - Log)
