The Ice Cream Parlor
Man: I'd like some chocolate ice cream.
Scooper: I'm sorry sir, but we're out of chocolate. Would you like something else?
Man: No, I really wanted some chocolate ice cream.
Scooper: I'm sorry, but we don't have that. Would you like to try a different flavor?
Man: Um... are you sure you couldn't find some chocolate ice cream in the back?
Scooper: I'm positive we don't have any. How about a different kind of ice cream?
Man: No, the only kind of ice cream I like is chocolate. Are you sure you don't have any?
Scooper: Look, Mister, can you spell the "van" in vanilla?
Man: V-A-N.
Scooper: Can you spell the "straw" in strawberry?
Man: S-T-R-A-W.
Scooper: Can you spell the "frick" in chocolate?
Man: But there is no "frick" in chocolate!
Scooper: That's what I've been trying to tell you!
