"Okay Bill the plan is simple Timmy's seventh birthday party starts at noon tomorrow outside near the park" Molly whispered. "Wait you actually want us to steal presents from a seven year old's friends and family seriously now" Bill hissed. "Don't be dramatic it's a goldmine Legos video games and envelopes stuffed with birthday cash everywhere untouched inside" Molly insisted. "Yeah and also frosting screaming kids clowns and parents filming every single second for Instagram live on Facebook" Bill muttered. "That's exactly why we go as entertainers you will be Mister Bouncy the terrifying cheerful clown again dear" Molly grinned. "I am absolutely not wearing that clown suit again last time I got pepper sprayed by grandma Ethel" Bill groaned. "It's foolproof you distract them with balloon animals while I grab the entire gift table quietly near entrance" Molly explained. "So I twist balloons while you stuff Paw Patrol toys and Nintendo Switches into a garbage sack quickly" Bill asked. "Exactly in and out in five minutes before the cake arrives nobody will even notice anything missing immediately" Molly promised. "And when little Timmy cries because all his presents vanished what do we tell his mother then huh" Bill wondered.
