I was sitting at lunch with a few friends, and we were all really bored. Chris has a Gatorade, half full. He puts a bag over the top and turns it over on the table, then pulls the bag out from underneath. The bottle is upside down on the table. The bell rings, we all get up, walk out. We watched through the door window to see the teachers pick it up and spill it.
Well, you might as well call a loving bomb squad, there all standing there trying to figure out how to pick it up with out spilling it. The loving biology teacher comes out of nowhere with a trash can and slides the bottle into the bin.
