1. Push over a little girl, who then falls over and gets a cut on her head and starts bleeding massively o-O (I've actually seen it, quite disturbing, I was like, 10 lol ._. poor kid. >.<)
2. Set something on fire in the changestall, and then walk out innocently ;P
3. Argue with the cashier, to the point of your mum taunts (seen that too, the y don't take it well)
4. Wear lingerie, and dance to Single Ladies in the middle of the toys aisle.
