Quote from : Harry Potter and the Goblet of Fire Movie

Cedric Diggory: I realize I never really thanked you properly for tipping me off about those dragons.
Harry: Forget about it. I'm sure you would've done the same for me.
Cedric Diggory: Exactly. You know the Prefects' bathroom on the fifth floor? It's not a bad place for a bath. Just take your egg and... mull things over in the hot water.
