I know you are but what am I

The best come back to any insult in the history of the planet. Using this phrase will completely destroy and annihilate your component, so only use of absolutely necessary. (Say they think Sam and cat is a good TV show)

Fred:Our mom just died

Joe:I know you are but what am I

I know you are what you said you are, so what am I?

The correct way to taunt on playgrounds. Often missaid as "I know you are, you said you are, but what am I?". Mostly by australians. Often shortened to "I know you are but what am I?"

Timmy: "you're a poop head"
Aaron: "I know you are what you said you are, so what am I?"
Timmy: *cries*

I know you are, you said you are, so what am I?

Blatantly useless retort which younger primary school students use.

Playground Bully: Ha ha! Ernie's Crap!
Ernie: I know you are, you said you are, so what am I?
Playground Bully: I just said that you were crap, though!
Ernie: I know you are, you said you are, so what am I?

I know you are, but what am I?

A retort with profound implications. Pee Wee's greatest contribution to youth culture.

Person A: You smell bad.

Person B: There's this thing about a small squirrel and how nobody loves you. Hi-ya! Now that's what I call a verbal bitch-slap.

Person A: I know you are, but what am I?

Person B: Haha what a complete fail of a a comeback. It's like, your face is all red, and you can't come up with a comeback.

Person A: It made no sense, but therein lies the point. The notion that one needs to respond with a rehearsed "comeback" is inane. Your squirrel-centric comeback was also inane; it failed to address your abhorrent smell, it seemed to mistake randomness for wit (really a squirrel?), and the mere fact that you would use it as an example of a verbal bitch-slap is laughable, as it lacks slap. It is quite slap-less. I respond to inanity with inanity.

Person B: Well, "your" still a faggot. And now I'm going to win this by blowing your mind with an ounce of inverse-Descartian drivel.

Person A: Nooooooooooooooo

I know you are, but what am I?

An amateur insult comeback. It is often regarded as one of the worst possible insult comebacks, being criticized for its lack of creativity, low versatility, and manipulation of English grammar in the word "you."

The comeback was popularized by a scene from the 1985 film 'Pee-Wee's Big Adventure,' in which Pee-Wee Herman repeatedly says the comeback after being told a string of insults by someone else.

Mark: You should have let me copy your test answers in class today.
Jim: No, it's against the rules. Stop relying on me to bail you out all the time. You're such a blowhard sometimes...
Mark: Oh, yeah? Well, you're a coffee whore whose father is on crack!
Jim: I know you are, but what am I?
Mark: You're a loser who doesn't let me copy your test answers in class!
Jim: I know you are, but what am I?
Mark: -_- seriously dude
