It's a Mystery, Charlie Brown

Linus:
Ashes to ashes, dust to dust. When there is a mystery, in Snoopy we trust.

Patricia "Peppermint Patty" Reichardt:
[to "Detective" Snoopy, thinking he's playacting] Your money or your life, you dirty rat!

Patricia "Peppermint Patty" Reichardt:
[seeing Snoopy and Woodstock run away to get Woodstock's nest] Hey, kid! Come back! We didn't finish the game! Come back, Snoooooop!

Linus:
Ashes to ashes, and dust to dust. Snoopy will find it, and find it he must.

Snoopy:
[holding up a broom straw] Aha!

Lucy:
That's a broom straw. So what?

Linus:
Ashes to ashes and dust to dust. The proof of the pudding is under the crust.
