Toilet Paper Prank

This prank works every time!!!! So funny!! :):):):) Please vote if you like my prank!!! Thanks

Put the toilet paper holder thingy at the edge of the things fastened to the wall like in the picture

Now wait outside the bathroom and listen carefully when someone is in there. When he/she is grabbing some toilet paper the whole thing should come down and scare the crap out of them!!! :):)
