Elaine: Can I have a medium Diet Coke?
Cashier: You want the medium or middle size?
Elaine: What's the difference?
Cashier: Well, we have three sizes: medium, large and jumbo.
Elaine: What happened to the small?
Cashier: There is no small. Small's medium.
Elaine: So, what's medium?
Cashier: Medium's large, and large is jumbo.
Elaine: Okay, give me the large.
Cashier: That's medium.
Elaine: Right. Yeah.
