Sherlock, Series 3

[Anderson has been telling Lestrade a convoluted theory that might explain how Sherlock survived the fall from St Barts' roof]

Lestrade:
Bollocks!

Anderson:
No, no, no, no! It's obvious! That's how he did it! It's obvious!

Lestrade:
Derren Brown? Let it go, Sherlock's dead.

Anderson:
Ah, is he?

Lestrade:
There was a body. It was him, it was definitely him. Molly Hooper laid him out.

Anderson:
No, she's lying. It was Jim Moriarty's body - with a mask on!

Lestrade:
A mask? A bungee rope, a mask, Derren Brown. Two years and the theories keep getting more stupid. How many more have you got for me today?

Anderson:
[Beat] Well, you know the paving slabs in that whole area, even the exact ones that he landed on, you know they were all...

Lestrade:
[Interrupting] Guilt. That's all this is. You pushed us all into thinking that Sherlock was a fraud, you and Donovan, you did this, and it killed him, and he's staying dead. Do you honestly believe if you have enough stupid theories it's going to change what really happened?

Anderson:
I believe in Sherlock Holmes.

Lestrade:
Yeah, but that won't bring him back.
