Kinda reminds me of the time I was walking downstairs with my arm full of bug bombs to my basement with one in my hand, finger on the trigger...
thought I was on the last step and found out there were still three steps left to go.
ending up face first on basement floor with an armload of bug bombs in your face isn't much fun, I can tell you that much.
Luckily, I already have a bad disc in my back, so I just made that hurt a lot. nothing new folks, go on home...
feel for ya bubba.
