Stargate SG-1, Season 4

Teal'c:
O'Neill, should we not be assisting Daniel Jackson with the translation?

Col. O'Neill:
I'm taking this loop off.

[Col. O'Neill starts squirting mustard and ketchup onto an empty plate.]

Col. O'Neill:
I'm telling you, Teal'c, if we don't find a way out of this soon, I'm going to lose it.

[Teal'c raises an eyebrow.]

Col. O'Neill:
Lose it. It means go crazy. Nuts. [from this point on, he becomes increasingly agitated] Insane. Bonzo. No longer in possession of one's faculties. Three fries short of a happy meal... [by now, O'Neill is ranting. He holds up his plate, which now has a crazed mustard-and-ketchup smiley face on it] WACKO!
