Molly pressed her binoculars against the window. "Seventeen kids, Bill. Seventeen screaming children hopped up on cake." "I've faced worse. Remember the nursing home job?" "Those seniors played dirty. One of them bit you." "Focus, Molly. What's our window?" "Musical chairs. They'll be distracted for approximately four minutes." "That's not enough time. We need a bigger distraction." "I could release the clown's doves early." "There's a clown? You didn't mention a clown, Molly." "Is that a problem?" "I have a thing about clowns." "A thing?" "A phobia, Molly. A deep, psychological terror." "You rob banks for a living." "Banks don't have giant red noses and honking horns." "Fine. You take the back entrance through the bounce house. I'll handle Chuckles." "His name is Chuckles?" "Bill, breathe. Remember, we're doing this for a good reason." "Are we though? We're literally stealing from children." "Children of Gerald Patterson." "The man who fired us from the circus." "And called you a talentless hack." "Those presents are ours. What's the signal?" "When the piƱata drops, we move." "I love it when a plan comes together." "You stole that line." "I'm a thief, Molly. It's what I do."
