The Pits.

[Cici and Ruby are having some cherries after finishing their breakfast cereal.]

CICI: Dad, Ruby's swallowing the pits.

DADAM: Ruby, don't swallow the pits.

RUBY: Yep.

CICI: Dad, she swallowed another one.

DADAM: Ruby, did you swallow another one?

RUBY: I didn't! [pause] It swallowed its own self.
