I forgot to mention what I discovered yesterday. Stick out your tongue and to the left and close your right eye. Then, as quickly as you can, switch your tongue over to the right, open your right eye, and close your left eye. Try alternating back and forth. It's very hard to do. If you're like me, you end up blinking both eyes rapidly and your tongue is wagging back and forth (and this when I try to do it slow). My apologies to anyone who tries this and gets caught.

I know you're probably wondering how I came up with this or even why. Well, I'll just leave it to your imagination.
