A Riddle, by Ethan

[Setting: Ethan is walking around aimlessly and occasionally antogonizing Josie; Sean is making pancakes; I am at the table eating cereal]

Ethan: Do you want to hear a riddle?

Sean:  Sure.

Ethan: A man rode into town on Friday and stayed for three days.  He left on Friday.  How did he do it?

Sean: He had a time machine.

Me: I have no idea.

Ethan: No!  His horse's name was Friday! Wasn't that funny?!

Sean: [looking at me] Wow, I haven't heard that since, well, elementary school!
