    "I've never sucked the head before." —Asa Butterfield

    Asa says, "You'd get a bottle of water like this, and then you poke a little hole in the bottom. And you walk around with your finger over the hole. Then, you take your finger off the hole and spray their crotch with water, and they have no idea!"
