"No, I use Ryan's computer when I do that."

 

From the TV archives, House had some great one-liners:

Cameron: We've got rectal bleeding
House: What, all of you?

***

Foreman: He has an acute scrotum
House: Adorable. ...
*Foreman gives him a look*
House: C'mon. How'm I not supposed to make that joke.

 

From the Simpsons (I did a quick search for it on Google and couldn't find it, so it might be a line that most people missed):

As Principal Skinner and Patty are on a date in the Space Need... er ... Sit-n-Rotate, it pans around to a guy on the ledge of a building with Chief Wiggum hanging out a window with a megaphone and all you hear is "Don't jump." Skinner and Patty don't notice and it never circles back to that building.
