Eddie: "Well, don't go putting none of that stuff on my sled Clark. You know that metal plate in my head?" Clark: "Ah! How could I forget?" Eddie: "I had to have it replaced, because everytime Catherine revved up the microwave, I'd piss my pants and forget who I was for about a half-hour or so. So, over at the VA, they had to replace it with a plastic one. It ain't as strong. So, I don't know if I ought to go sailing down no hill with nothing between the ground and my brain but a piece of government plastic." Clark: "You really think it matters Eddie?" Eddie: "Well, see the plate runs right underneath the part here. See, over here, nothing. But, here if this gets dented, then my hair just ain't going to look right."
Eddie is thinking about sledding, but doesn't want the special oil, because of the plate in his head--he doesn't want his hair to be ruined.
