LOL good luck, bro! If I were you though, I would try butterflying sum one's locker that you know the combo to, that way you don't have to go around the whole school yanking on the locks. For sum reason though, it's easier to yank the locks open once you get experience. Again, good luck!
Gah, first Rebecka then you... It's a classic Middle School/High School prank! It means yanking on their locker locks and if ur lucky it'll come undone. Then, you put the lock back on backwards and then scrambling the number up. Sumtimes I like to write "you've been butterflied" on thier locker door with a sharpie.
Ooooh, okayz, I drink it occasionally... anywayz I made another youtube vid... plz go watch it, big borther! ^^ Oh but before you do I'd like to tell you that I butterflied like... 18 lockers 2day and I didn't even get caught! yay I'm such a nerd.
