Molly and Bill crouched behind a hedge, plotting to break into a kids' party where forty balloons bobbed above a mountain of gift-wrapped boxes. A bouncy castle wheezed nearby, and somewhere a child shrieked with joy. "Okay, here's the plan," Molly whispered, straightening her clown wig. "When I give the signal, you smash the piƱata. Kids dive for candy, nobody guards the presents, and we walk out with every last one." "Why do I have to be the one with the bat?" Bill asked, nervously tugging at his fake mustache. "Because you're the strongest. You're a mime, so nobody can interrogate you." Bill gasped. "I'm a mime?" "Mimes can't answer questions, Bill. It's basic." Bill nodded solemnly, then knocked over a garden gnome with his elbow. He caught it inches from the patio, freezing as a grandmother turned around. "Smooth," Molly hissed. "I'm nervous, Molly." "Then be nervous silently. You're a mime." Across the lawn, a small brown pony wore a party hat and an air of smug contentment. "Molly, is that a pony?" "Yes, Bill, it's a pony." "Can we take the pony? He's got a cute hat." "We are not stealing a pony." "Yet," Bill said, grinning wickedly.
