Children Are Hazardous to Your Health

Children do get their fair share of owies and boo-boos. Unfortunately, so do their parents because of them.
For me, there's the everyday head bonks that come from Jude, who in his excitement, forgets his head is hard as cement and bashes it into my face. Then there's Rocky, who is teething. Enough said.
But every once in while along comes the rare injury, like when Jude dropped a heavy wooden block on my foot and broke my toe. Granted it was just the little toe, but that incident sent me to the next room (hopefully out of earshot) with a mouth full of F's and SH's.
Most recently, however, I was awaken by a framed poster crashing down on my face. Thank-you, Rocky.
How did it happen? How does any of this happen?

Here's the recipe:

1 part curious child
1 part sleeping, distracted or otherwise non-suspecting, never-think-it's-gonna-happen parent
something(s) hard (preferably with sharp edges)

Cook for .000000001 second

Viola! Injury a la mom.
