I have the funniest story.

My 4 year old son was standing on the bed, standing on his head, "walking" up the wall with his feet. He was trying very hard to do this headstand, and really putting a lot of effort into it.

My husband asked him what he was doing, and he said, "I'm trying to get the money out of my pocket!"

Eventually he gave up and did it the old fashioned way - by reaching into his pocket with his hand.

I love that efficiency wasn't a requirement for him. Next time I need change for a payphone, I'll have to do a headstand to get it!
