Amy
Penny's friend, Zack, stopped by and said "hello" and I said "hoo!"
Sheldon
Hoo?
Amy
Zack.
Sheldon
Then why did you ask?
Amy
Ask what?
Sheldon
Who?
Amy
Zack.
Sheldon
Alright, let's start over. What did you say when Zack walked in?
Amy
Hoo!
Sheldon
Zack.
Amy
Why do you keep saying 'Zack'?
Sheldon
Because you keep saying 'Who'.
Amy
I'm not saying 'hoo' now. I said 'hoo' last night.
Sheldon
And the answer was Zack, correct?
Amy
There was no question; I simply said "Hoo!"
Sheldon
[short pause] All right. I think I have enough to go on.
