Discworld Giftshop - Presents for the Terry Pratchett Fan

During his appearance at a theatre in Berlin, promoting his new book Thud!, famous comic fantasy writer Terry Pratchett tells a dirty joke. Sorry for the lack of steadiness there, it was shot using 12x zoom and without anything to rest my arms on. That excuse enough? ;) Transcript following. PLEASE DO NOT READ ON IF YOU DON'T WANT TO SPOIL THE PUNCHLINE FOR YOURSELF! ----------- [...] but it should not affect [minors etc.]. I like the pure mathematics of the joke. A man goes into a pub, carrying an alligator under one arm. Puts it down on the table. And he says:"I've got a trick. I bet there's no one here who is prepared to do this." He opens the alligator's mouth and..well...um.. reveals a certain part of his own...anatomy, which he places therein. And then he brings down his hand on the alligator's head, like this BAMM! He blinks a little while and then he says: "Is there anyone here prepared to do that?" There's a long pause, and then an old lady at the back of the pub gets up and says: "I don't mind giving it a try but you mustn't hit me so hard on the head."
