I’m Not Drunk

This is a humor staple. The most common form is when the person in question attempts to convince someone else that he’s ok (mentally or physically) and so mangles the assurance that it is self-defeating.

Drunks are great at this. No matter how they phrases their denials, (“I’m not drunk, it’s just that people keep moving the floor on me”) , they fail to convince anyone.

Here’s a not-so-classic example, from Short Circuit 2:

[after the robot, Johnny Five, gets all torn apart by the bad guys]
Fred: Are you ok?
Johnny Five: Functioning 100%. Perfectly KO Derf.
Fred: It's Fred.
Johnny Five: That's what I said, Derf.

Homer Simpson has provided us with a wealth of these:

• Oh, Lisa, you and your stories: Bart's a vampire, beer kills brain cells. Now let's go back to that... building...thingy... where our beds and TV... is.
• I hope I didn't brain my damage.
