School prank on the news

[Knipples]

Well it made me laugh! Pupils in a school in America decided it would be funny to rearrange all their classroom furniture on the roof of their buildings.

I might try and get the kids to do this tomorrow, anyone else get up to any pranks at school?

Last year the 6th formers when they were leaving got hold of 5 pigs, they numbered them 1, 2, 3, 4, and 6 and then set them free in the school surroundings. The five were rounded up eventually, but then staff spent hours searching for "Pig number 5" - who of course didnt exist!
