This morning, the impossible happened. I was playing with my two babies, with a string. Both were playing happily, until the unthinkable happened...

I flipped the string to them, they both leaned forward, and--

BONK!

They banged their heads together! They leaned back, blinked, swatted each other once for good measure, then went off to lick their wounded pride.

It took me a solid ten minutes to stop laughing...
