QI, Series Two [B]

Alan Davies:
Why did the mushroom go to the party?

Jo Brand:
No. No.

Stephen Fry:
No, not that joke. Why did the mushroom go to the party, Alan?

Alan Davies:
Cos he was a fungi. [The audience groans.] What's wrong with that joke, then?

Jo Brand:
That's a joke for, like, an imbecile. You know, like nought point seven years old.

Alan Davies:
What's brown and sticky?

Jo Brand:
Oh, no... I don't kn- yeah, I do...

Alan Davies:
A stick.

Jo Brand:
Yeah... [Exasperatedly puts her head down.]

Stephen Fry:
I'm worried by the audience reaction...

Alan Davies:
What do you call a boomerang that won't come back?

Jo Brand:
A stick.

Alan Davies:
A stick.

Stephen Fry:
Do you have any other jokes where the punchline's "a stick"?

Alan Davies:
Loads!

Stephen Fry:
Oh, right.

Alan Davies:
What's orange and sounds like a parrot?... A carrot.

Stephen Fry:
What's red and silly?... A blood clot. [The audience groans, Alan grimaces] Oh, don't look at me like that, you f***ing pig-eyed sack of shit! Don't you do that!

Alan Davies:
You've spoiled it. What's red and sits in the corner? A naughty strawberry.
