The one I used to know as the Irish knock knock joke (but wouldn't call it that now of course, as mentioned in a previous post; probably I'd just call it a different knock knock joke!) went like this:

Person A: Do you want to hear a knock knock joke?
Person B: Yes, go on.
Person A: Ok. You start.
Person B: Knock knock
Person A: Who's there?
Person B:

Knock knock.
Who's there?
Euripides.
Euripides who?
Euripides trousers, you menda dese trousers! (Said in an Italian accent!)

You have to be holding a glass of water before you start.

Knock knock
Who's there?
John
John who?
John the Baptist (dip fingers in glass and flick water in the other person's face)

This knock knock joke works better in real life.
