Thats interesting...
When I was going to HS there was a gas station next to the school were I'd get food/drink for breakfast...I baught a cup of coffee and a bag of chips payed with a 20 got like a 10 a 5 and 2 1's back....as I'm leaving a friend asks me to buy him a pack of smokes (I owed him $% anyways) so I went into the store and baught the smokes and they called the cops cause the $5 was fake... ya it was funny try explaining "the cops thought i was counterfieting money..." to your teacher
