Brad: Well, why do I have to learn how to multiply compound fractions? I'm never gonna use them.
Tim: You use 'em every day.
Brad: When?
Jill: Well, like, when I go to the grocery store and I buy a pound and a half of cheese.
Brad: Yeah, but you're not multiplying anything.
Jill: Well, you didn't let me finish.
Tim: Why don't you finish that?
Jill: Well, I buy a pound and a half of cheese and then I multiply that by... a gallon and a half of milk.
Brad: But why would you do that?
Jill: Because... Because I'm... making cheese milk.
Jill: Now go get your math book. We are going to teach you how to multiply compound fractions.
Tim: Couldn't we just punish him? Send him in his room without his cheese milk? [Jill laughs]
