re: which "Vacation" movie is the best

"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 Cathrine 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."
