The Wacky Math of Abbott and Costello

The comedy team of Bud Abbott and Lou Costello, probably most famous for their "Who's on first" baseball routine, also made arithmetic shenanigans the basis of several of their comic dialogues in their movies and television programs.

Abbott and Costello became a comedy team in 1936, becoming popular on the burlesque stage, then achieving wider acclaim by performing on radio. Released in 1941, their second movie, Buck Privates, was a box office hit. In this World War II comedy, Abbott and Costello play tie salesmen who accidentally enlist in the army to avoid getting arrested.

One mathematical bit in Buck Privates involves a word problem reminiscent of those spoofed by John Scieszka and Lane Smith in the delightful children's picture book Math Curse.

Abbott: You're 40 years old and you're in love with a little girl that's 10 years old. You're four times as old as that girl. You couldn't marry that girl, could you?

…

Abbott: So you wait 5 years. Now the little girl is 15, and you're 45. You're only three times as old as that girl. So you wait 15 years more. Now the little girl is 30, and you're 60. You're only twice as old as that little girl.

Costello: She's catching up.

Abbott: Here's the question. How long do you have to wait before you and that little girl are the same age?

Costello: Well…What kind of question is that? That's ridiculous. If I keep waiting for that girl, she'll pass me up. She'll wind up older than I am. Then she'll have to wait for me!

Fast-talking, inveterate con man Abbott had a sneaky way with numbers (aided by mangled logic), especially when they had dollar signs next to them. Here's another encounter from Buck Privates, one echoed in several later movies and shows.

Abbott: Do me a favor. Loan me $50.

Costello: I can't lend you $50. All I've got is $40.

Abbott: That's okay. Give me the $40, and you'll owe me $10.
Costello: How come I owe you $10?
Abbott: What did I ask you for?
Costello: $50.
Abbott: What did you give me?
Costello; $40.
Abbott: So you owe me $10.
Costello: That's right. But you owe me $40. Give me my $40 back.
Abbott: There's your $40. Now give me the $10 you owe me. That's the last time I'll ever ask you for the loan of $50.
Costello: How can I loan you $50 now? All I have is $30.
Abbott: Give me the $30, and you’ll owe me $20.
Costello: This is getting worse all the time. First I owe you $10, and now I owe you $20!
Abbott: So you owe me $20. Twenty and 30 is 50.
Costello; Nope! Twenty-five and 25 is 50.
Abbott: Here's your $30. Give me back my $20.
Costello: All I've got now is $10!

Abbott then entices Costello into a silly, double-or-nothing number game.

Abbott: Take a number, any number at all from 1 to 10, and don't tell me.
Costello: I got it.
Abbott: Is the number odd or even?
Costello: Even.
Abbott: Is the number between 1 and 3?
Costello: No.
Abbott: Between 3 and 5?
Costello: No. I think I got him.
Abbott: Between 5 and 7?
Costello: Yes.
Abbott: Number six?
Costello: Right… . How did he do that?

Toward the end of the movie, during a boxing match, Costello is knocked to the canvas, and the biased referee gives a quick count: 2, 4, 6, 8, 10.

Costello: What's this? 2, 4, 6, 8, 10? What happened to 1, 3, 5, 7, and 9?

Ref: I don't like them numbers. They're odd.

Such nuggets of mathematical fun turn up not only in Buck Privates but also in other Abbott and Costello movies and later in sketches from their television programs. The 1941 film In the Navy, for example, features a hilarious episode in creative counting. Costello comes up with three different ways to prove that 7 times 13 equals 28.

If you look and listen closely, you'll find an amazing amount of number play in those old Abbott and Costello movies and TV programs.
