Run Yourself To Sleep

Lately one of the funniest things has happened before going to sleep. My wife claims that she's too awake and can't go to sleep, my response is that she should go running or something like that to get tired.

For the next 20-30 seconds she wiggles her legs back and forth under the covers 'running' and then as soon as she stops in under a minute, she's out cold.

I don't know how she does it, but she 'runs' herself to sleep, and it's getting hard not to laugh at how effective it is.
