First, toss the pocket-knife away. It's not necessary.

Second: storm a bank, with chaotic clowns and all.

I'm talking: clowns all over the lobby...

clowns crowding the outside side-walk for a block away...

clowns performing circus tricks, magic tricks, and gymnastic tricks...

mime-clowns... dancing clowns... clowns with fire-engine ladders... clowns with water-squirting flowers... clowns with monkeys...

clowns with big shoes tripping other clowns with smaller shoes on purpose...

police-clowns with oversized foam-billyclubs, bonking other clowns on the head...

clowns with squeaky clown-horns... clowns with kazoos... clowns with vuvuzelas -- an intensity of ruckus and racket.

All the while, the ordinary people, bank tellers, bank managers, and bank customers run screaming in horror, in all directions, trying to flee the crowded noisy sea of performing clowns.

NOW... Inside the bank, that's the time to pop/unfurl a dazzling multicolored parachute, add to the circus like chaos, bringing even more obscurity (and also blocking the camera views).

That's also the time you start loading up the bags with money. As much money as your greedy little hands can grab.

FINALLY...

You should also have plenty of time to make your getaway, as the police storm the bank lobby, and try to sort it all out, in a tangled mess of parachute cord, laughing tricky clowns, parachute material all over the place.

If all goes well, you will now be rich, and no one will have been harmed (unless of course it's the trigger happy kind of cops with clown phobia... leaving an aftermath of dead clowns and blood, which will then go on to be known as the Great-Clown-Massacre-Caper-of-2015).
