Lol my younger brother got shown that and can't stop singing it!!! xDBring a recording of the song that Snape, Dumbledore, Hermione, Harry Potter, Ron Weasly did in "Harry Potter Puppet Pals-The Mysterious Ticking Sound" and pretend your singing it (LAWL)
Er.....
1. Try and walk out the shop with, say, a toy or food or something, and when the beeper things go and the manager or whoever comes to see whats happening, say, "It said 'Get one free'." {As long as whatever you're taking has a BOGOF ~ Buy One Get One Free}
2. Act as if you've just shoplifted, darting your head around to make sure no one is looking at you. Hold something in your cardigan/jumper as long as it isn't real!
I know they aren't very good but oh well!!!
Best Wishes,
