Dash: "I bet you that you can't catch Twilight with a book."
Shepherd: "I... Why?"
Dash: "Because it would be funny."
Shepherd: "And the stakes?"
Dash: "... Twenty bits."
Shepherd: "You're on."

Shepherd: "Hmmm... I need to be really diabolical about this..."
He puts a book entitled "DON'T READ THIS BOOK" under a box held up by a stick
And hides
And waits
Dash: Hiding with him "She won't fall for it."
