Harry Potter and the Goblet of Fire2005

George:
Thank you, thank you. Well, lads, we've done it.

Fred:
Cooked it up just this morning.

Hermione:
[sing-song] It's not going to work.

Fred:
Oh yeah? And why's that, Granger?

Hermione:
[indicating a magical line drawn around the base of the goblet] You see this? This is an age line. Dumbledore drew it himself.

Fred:
So?

Hermione:
So, a genius like Dumbledore couldn't possibly be fooled by a dodge as pathetically dimwitted as an aging potion.

George:
Ah, but that’s why it's so brilliant.

Fred:
Because it’s so pathetically dimwitted!

[the twins shake up the bottles and prepare to drink the contents]

George:
Ready, Fred?

Fred:
Ready, George.

Fred and George:
Bottoms up.

[They jump inside the age line, and cheer. They put their names in the flame and high-five. The flame fires up and they're flung across the room onto the floor. When they get up they have full heads of grey hair and beards]

George:

Fred:
You said…

[They roll around fighting on the floor and the crowd cheer. The room suddenly becomes silent as Viktor Krum walks in and puts his name in the flame. He looks at Hermione and she smiles]
