That looks like a great prank though. I'm inclined to try it on my wife. Reminds me of the joke:
What did the redneck say before he dies?
"Hey ya'll, watch this!"
What'd the second redneck say before he dies?
"Aww, I can do that."
What'd the third redneck say?
"Now ya'll ain't doing that right, let me show ya."
On second thought, maybe I won't pull that one on the wife. Just found out she's pregnent, and you don't want to scare a pregnent woman!
