Chunnel

There's an Englishman, a Frenchman, a bird with big boobs and an old granny sitting in the same compartment of a train.

The train enters a tunnel and all goes dark. In the darkness the sound of someone being slapped is heard.

When the train emerges from the tunnel, the Frenchman has what is clearly the mark of a hand on his face.

He looks at the bird with the big boobs and thinks:
The English pig has tried to touch her up in the tunnel. She thinks it was me and slapped my face.

The bird with the boobs looks at the Frenchman and thinks:
I bet he tried to touch me up, but touched the old lady by mistake and got a slap for it.

The old lady Looks at the Frenchman and thinks:
Dirty French sod has touched up the pretty girl and got his face slapped.

The Englishman thinks:
Can't wait for the next tunnel so I can smack the frog again.
