One of my personal favorite underrated sketches was a cold upen in the fall of 1988. Matthew Broderick was hosting and he was playing Dan Quayle. He's walking around, and everybody is talking about him being the Vice President and he goes to his room. Jan Hooks walks in and says I'm sorry I thought this was the bathroom.
Quayle: Oh that's all right, Mrs. Reagan. You can come in.
What follows is a hysterical parody of the Graduate with all the lines used that you'd expect
"Mrs. Reagan, you're not trying to seduce me are you?" will still crack me up every time I see it.
