WNEP) -- A family in Union County pulled an elaborate April Fools' Day prank on a mail carrier.
The Kelly family created an extra-long envelope that they left sticking out of their mail slot at their home in Lewisburg.
It was addressed with a stamp and everything.
The family waited in the car, and when the mailman came, they watched as he kept pulling and pulling until the envelope said "April fools!"
We wonder how the mail carrier might get them back next year.

The Hoff pasted to the back of her car , someone was in that front room playing video games or something and never saw us do any of this.
It's easy to find the poster I added, but I can't take credit for it. I read about some genius posting these around New York City. I found it hillarious, and so did anyone I showed it too. It went over pretty well... for a few hours. But once again, someone without a sense of humor took these down too.
Do give this one a try! (IF you have no printer, you can always sketch a fish on paper, right?) Works excellent on colleagues, fellow students, family members and random strangers.
