Not bad here is one for the road.

Sitting in a compartment on a train were the tooth fairy, an expensive accountant and a cheap accountant. On a table between
them was placed a briefcase full of money.

Suddenly the train entered a tunnel and everything went dark. When the train exited the tunnel and the light returned, the
briefcase was gone. Who took the briefcase?…

Well, it’s obvious really. It had to be the expensive accountant as there’s no such thing as the tooth fairy or a cheap accountant!
