Two and a Half Men, Season 6

Alan:
So what's the deal? Does, uh, Chelsea have a cold?

Charlie:
I'm not sure. Cold, flu, something disgusting.

Jake:
Maybe she has an STD.

Charlie:
What?

Jake:
It means "sexually transmitted disease".

Charlie:
I know what STD's are!

Alan:
Your uncle helped invent them.

Jake:
You know, they can be prevented by using a condom.

Charlie:
I know we could have prevented you by using a condom. Now we gotta use a hammer.

Jake:
I don't understand.

Charlie:
Go get me a hammer, and I'll show you.

Jake:
Okay. (walks to the utility room)

Charlie:
(to Alan) You must be so proud.

Jake:
(from the utility room) Ballpeen or claw hammer?

Alan:
Do me a favor. When he comes back, just do it.
