"Behzad the Horse: The best thing you can do is leave traces of poo in the way. Because they're actually not looking at all on the ground, they're looking at the girls around them. They step on it, they walk with it, then starting to smell. So they blame each other, and they're looking at the sole of the shoe, then that's it, they've been hit by us. [chuckles] You show them you can be dangerous, but in a smelly way."
