Molly, this is insane. We're not breaking into a bloody children's party. Oh come on, Bill. Think of it as the ultimate soft target. Fifty screaming kids, one distracted magician, and a mountain of brightly wrapped presents with our names on them. Our names aren't on them, Mol. Metaphorically, you walnut. Look, we hit it during pass the parcel. All the little monsters will be blindfolded and fighting over that sad bit of sellotaped cardboard. That's our window. You're suggesting we nick Barbie dolls and plastic dinosaurs in front of thirty parents? We wear the mascot costumes from the van. I'll be the six-foot rabbit, you can be the depressed bear. Nobody looks directly at mascot costumes, it's a scientific fact. This is the stupidest idea you've ever had, and you've had some shockers. Last week you said we should rob the Queen by hiding in a corgi. This is practically genius by comparison. Now shut up and help me practice my high-pitched excited voice for when we burst in. Please don't. Woooo! Happy birthday Timmy! Where's the presents then, you tiny gremlins? I'm divorcing you after this job.
