LOL! What a prank!
It's funny, we've not really done very many pranks in my household--at least within my memory.
Once me and two of my older siblings were in the dining room. There was a big window where the sun poured through, really hot. We were discussing how you can use a magnifying glass to set something on fire using the sun, and my brother got one and held it up so we could see how it focused the light. He had it focused on a chair, and suddenly I screamed, "It's smoking!" My sibs were like, "nah, it couldn't do that, it's not hot enough!" But I I insisted, "It really IS smoking guys!" Then they were like, "oh, no," and put the magnifying glass down, and the chair had three burn spots in it! 
Completely unrelated What's the definition of a geek @everyone? I think I know what it means, but someone called me that the other day, and I'm curious...what does "geek" mean to you?
