Molly and Bill crouched behind the bounce house. "Bill, tell me again why we are robbing a kids party for presents?" "Because, Molly, six year olds get the best loot with zero security guards." "That is morally bankrupt and also brilliant, but clowns scare me to death." "Relax, I bought us clown suits so we blend right in with entertainment." "You look less like a clown and more like a sad haunted birthday balloon." "Perfect, fear is my disguise. Now what is the plan for grabbing gifts?" Molly adjusted her red nose. "We walk in singing happy birthday, stack presents by the back door quietly." "Then we shout cake time really loud and run out with the giant pile?" "Exactly, kids cry over cake, parents film it, nobody watches the shady clowns." "What if someone asks for balloon animals? I only know how to make snakes." "Just cry fake clown tears until they leave you alone and want refunds." "Genius. I will distract with magic tricks while you haul Lego sets outside." Bill grinned, tugging his wig. "Deal, but if I get hit by a juice box again, you owe me extra candy." "Agreed, let us steal everything." They laughed.
