You’re 40, she’s 10 – A classic  Abbott and Costello skit, where  Bud Abbott tries to play a prank on  Lou Costello, only for Lou to use his clownish math skills.

Slicker Smith (Bud Abbott): You’re 40 years old and you’re in love with this little girl that’s 10 years old. You’re four times as old as that girl and you couldn’t marry her, could you?
Herbie Brown (Lou Costello): Not unless I come from the mountains.
Slicker Smith (Bud Abbott): All right- you’re 40 years-old, you’re four times as old as this girl, and you can’t marry her, so you wait five years. By that time the little girl’s 15 and you’re 45. You’re only three times as old as that little girl. So you wait 15 years and when the girl is 30, you’re at 60. You’re only twice as old as that little girl.
📷****Herbie Brown (Lou Costello): She’s catching up.
Slicker Smith (Bud Abbott): Yes, yes. Now here’s the question. How long do you have to wait until you and that little girl are the same age?
Herbie Brown (Lou Costello): Now what kinda question is that? That’s ridiculous!
Slicker Smith (Bud Abbott): Ridiculous or not, answer the question.
Herbie Brown (Lou Costello): If I wait for that girl she’ll pass me up. She’ll wind up older than I am.
Slicker Smith (Bud Abbott): What are you talking about?
Herbie Brown (Lou Costello): She’ll have to wait for me!
Slicker Smith (Bud Abbott): Why should she wait for you?
Herbie Brown (Lou Costello): …I was nice enough to wait for her!

One of the classic  Abbott and Costello  routines, where Bud Abbott takes advantage of a common math mistake that we all make to fleece his pal, Lou Costello, out of all of his money.  The skit ends with a simple ‘read my mind’ routine that takes Lou’s last remaining bill.  This routine was done  many  times, both in the movies and their radio show.

Bud Abbott: Do me a favor, loan me $50.
Lou Costello: Bud, I can’t. I can’t loan you $50.
Bud Abbott: Oh, yes, ya can.
Lou Costello: No, I can’t. All I got is $40.
Bud Abbott: All right, give me the $40 and you’ll owe me 10  
Lou Costello: Ok, I’ll owe you 10.
Bud Abbott: That’s right.
Lou Costello: How come I owe you 10?
Bud Abbott: How much did I ask for?
Lou Costello: 50
Bud Abbott: How much did you give me?
Lou Costello: 40.
Bud Abbott: So you owe me $10.
Lou Costello: That’s right.  [Pause] But you owe me 40.
Bud Abbott: Don’t change the subject.
Lou Costello: I’m not changing the subject; you’re trying to change my finances. Come on, Abbott give me my $40.
Bud Abbott: All right, there’s your $40, now give me the 10 you owe me.
Lou Costello: I’m paying you on account.
Bud Abbott: On account?
Lou Costello: On account I don’t know how I owe it to ya.
Bud Abbott: That’s the way you feel about it, that’s the last time I ask you for a loan of $50.
Lou Costello: But how can I loan ya $50, now. All I got is 30.
Bud Abbott: Well, give me the 30 and you’ll owe me 20.
Lou Costello: Ok. This is getting worse all the time. (Look at audience) First I owe him 10, now I owe him 20.
Bud Abbott: Well, why do you run yourself into debt?
Lou Costello: I’m not running in, you’re pushing me!1
Bud Abbott: I can’t help it if you can’t handle your finances. I do all right with my money.
Lou Costello: And you do all right with my money too.
Bud Abbott: Now I asked you for a loan of $50. You gave me 30, so you owe me 20. 20 and 30 is 50.
Lou Costello: No. No. No. 25 and 25 is 50.
Bud Abbott: All right, here’s your $30, now give me the 20 you owe me. Fine guy, won’t loan a pal $50.
