Funny line

Heard a funny line in an episode of a tv show that was on at our house this weekend. The person was being pressed for how soon they would do something after having just told them they would do it soon.

"I will do it soon. You know . . . when the big hand is on the 'S' and the little hand is on the 'oon'."

Must remember that one next time the kids ask me when we are going to do something.
