Mein Lieblingswitz auf Englisch:

In a poets' contest the participants had to make up small fourliner; a word that was given to them seconds before they started had to be included.
In the final round a Rabbi from Jerusalem and an Australian shepherd had to insert the world "Timbuktu".

The Rabbi had to begin:

I have been a Rabbi all my life
Had neither children nor a wife.
I've read the Bible through and through
On my way to Timbuktu.

The audience cheered, but then the shepherd commenced:

Well, one day, when Tim and I from Canberra to Sydney we went
We met three beautiful women in a tent.
As they were three and we were two,
I booked one and Tim booked two.

The shepherd won.
