No, I'm not an Ood, despite the dangly things. That's my scarf. Oh, and that's me in the lift leaving the office to go home. Home to listen to youngest telling me Knock Knock joke after Knock Knock joke. Here's the best:

Knock, knock
Who's there?
Granny
Granny who?
Knock, knock
Who's there?
Granny
Granny who?
Knock, knock
Who's there?
Granny
Granny who?
Knock, knock
Who's there?
Granny
Granny who?
Knock, knock?
Who's there?
Auntie
Auntie who?
Aren't ya glad Granny's left?

He mixed it up a bit with other jokes:
Why do French people eat snails?
Because they don't like fast food.

Maybe it's the wine, but youngest's jokes had me giggling. Or maybe it was hearing him belly-laugh after each joke :-)
