Hiccupping Kimi: Oh, Dr. Alonso, Dr. Montoya, Dr. Alonso Is it true that an apple a day keeps the doctor away?
Dr. Montoya: Yes, that's true.
Hiccupping Kimi: Well, then, why don't the patients eat an apple a day and save hospital expenses?
Dr. Alonso: Pardon me if I laugh. Nyuk, nyuk, nyuk, nyuk, nyuk, nyuk, nyuk, nyuk, nyuk, nyuk, nyuk, nyuk, nyuk! That's a pippin!
Hiccupping Kimi: Oh, I know what a pippin is.
Dr. Alonso: You do, eh? What's a pippin?
Hiccupping Kimi: Uh, a pippin is an apple with a skin on the outside.
Dr. Montoya: Did you ever see an apple with a skin on the inside?
Hiccupping Kimi: Oh, sure I did.
Dr. Alonso: You did?
Hiccupping Kimi: Uh-huh.
Dr. Alonso: Where?
Hiccupping Kimi: In homemade apple pie.
