I have a tall, narrrow dog. Narrow enough that when he rolls over on his back for a tummy rub, he doesn't balance very well. Consequently, I knocked him off balance while rubbing his tummy. He kicked out with a back leg to get balanced again, and my face happened to be in the way. Funny how I was more concerned about whether or not my eyeball was still intact (it was) than whether or not my cheek and eyelid were (they were, just scratched and stinging like the dickens). Or maybe not so funny, as it's easier to mend torn flesh than regrow a gouged-out or otherwise damaged eye.
Somehow, this didn't end up being nearly as amusing as I thought it would be. I guess I'm just not very funny.
