- You say the cutest things.

- On Halloween night, the Great Pumpkin rises out of the pumpkin patch then flies through the air to bring toys to all the good little children everywhere.

- Wouldn't you like to sit with me in the pumpkin patch on Halloween night, and wait for the Great Pumpkin?

- Oh, I'd love to, Linus.

- What's going on here? What are you trying to do to my little sister?

- Hey! I got an invitation to a Halloween party!

- Is the invitation to Violet's party, Charlie Brown?
