A number of years back, bank robbery, Richmond VA. Thief shoved bag at teller, demanded all her money. She put everything in the bag. He shoved bag into the top of his pants, ran out of the bank.
Wait for it.
EVERYTHING included a dye pack. Looks like a bundle of bills. Contains permanent dye, tear gas, an explosive charge, and a radio activated timer. If carried out of bank, 30 second timer starts ticking.
He was one block away when the timer ran down. The bag had slipped to the crotch of his undies.
Yes, he was eligible for a Darwin Award- by removing himself from the gene pool.
