Here is a transcript of the famous 'who's on first' dialogue between Lou Costello and Bud Abbott.
LOU: I love baseball. When we get to St. Louis, will you tell me the guys' name on the team so when I go to see them in that St. Louis ball park I'll be able to know those fellows?
BUD: All right. But you know, strange as it may seems, they give ball players nowadays very peculiar names, nick names, like "Dizzy Dean." Now on the St. Louis team we have Who's on first, What's on second, I Don't Know is on third --
LOU: That's what I want to find out. I want you to tell me the names of the fellows on the St. Louis team.
BUD: I'm telling you. Who's on first, What's on second, I Don't Know is on third --

BUD: Every dollar of it. And why not, the man's entitled to it.
