"Right," said Molly. "Two o'clock, the bouncy castle goes up. That's our window." "Our window is a bouncy castle?" "The *distraction* is a bouncy castle, Bill. Keep up." "And the presents?" "Stacked on the trestle table by the gazebo. Forty-odd gift bags, minimum. Some of them have iPads in." "Seven-year-olds with iPads." "Don't get political, we're working." "I'm just saying, when I was seven I got a satsuma and a clip round the ear." "Which explains a great deal. Now. You'll be the entertainer." "The what?" "Mr. Bibbles. Balloon animals, magic tricks, the works. I've got the costume in the van." "Molly." "It's mostly polyester." "Molly, I can't do balloon animals." "You can do a sausage dog." "I can do a sausage." "That's a dog if you say it confidently." "And what are you doing while I'm humiliating myself in front of a horde of sugared-up infants?" "Loading the van. Twelve minutes, in and out, and we're eating steak by teatime." "What if a kid clocks me?" "They're seven. Deny everything." "That's your plan? Deny everything?" "It's held up in court twice, Bill." "Fine. But I'm not doing the voice." "You'll do the voice." "...I'll do the voice."
