About what?

You serious? You don't know.

Everybody knows you never go
full retard.

What do you mean?
- Check it out:

Dustin Hoffman; Rainman.
Looked retarded, acted retarded. Not retarded.

Count toothpicks, cheat at cards.
Autistic, sure. Not retarded.

Then you got Tom Hanks;
Forrest Gump.

Slow, yes, retarded, maybe,
braces on his legs.

But he charmed the pants off Nixon,
and he won a Ping-Pong competition.

That ain't retarded.

And he was a goddamn war hero.
You know any retarded war heroes?

You went full retard, man.

Never go full retard.

You don't buy that?
Ask Sean Penn, 2001; I Am Sam.
