Unknown Wife tells me, "UP, there's a small wasp nest by the garage door. Could you get it?"
So, I get the wasp spray and give it a shot. A few wasps come flying out, I take two quick steps back, and trip backwards over my own two feet.
End result: I land on my butt and wrench my back. And all Unknown Daughter (age 5) registers is that "Daddy said a bad word."
That's why they make those words (and ibuprofen).
