[describing the metal plate in his head]

I had to have it replaced 'cause every time Katherine revved up the microwave, I'd piss my pants and forget who I was for a half-hour or so. So, they put in a plastic one, and it ain't as strong, so...I don't know if I ought to go sailin' down no hill with nothin' between the ground and my brains but a piece of government plastic.

Do you really think it matters, Eddie?

[gesturing over the left side of his head]

Well, you see, the plate runs underneath my part here, and over here is... [bangs his right side] Nothing. But here, if this gets dented, then my hair just ain't gonna look right.

Yeah, I know the feeling.
