Who had the best Halloween costume at your school today?
Buster: There's this guy, and you can't make him laugh at anything. He had a ninja costume, and that was the best one.
He never laughs at anything?
Well, you can't make him laugh.
I'll bet I could make him laugh.
No.
I'll bet I could.
How would you?
I'd tell him a joke.
What joke would you tell?
Knock knock.
Who's there?
Butt.
Butt who?
Buttsy McButtbutt.
Don't know if it would work on that kid, but Buster and Daisy have been laughing for two days, and Dad just stopped.
