From the People of Walmart site.  I guess someone always wanted to wipe their butt with a dollar bill.

MONEY IN THE BANK

As my husband, our good friends and I were leaving Walmart one night my husband spots what he thinks is a wad of dollar bills on the ground. He picks it up only to discover it is $1 wrapped around a piece of poo.

Freaked out he drops the money and we look around for the hidden cameras and hand sanitizer. That had to have been a prank. Who would wrap a piece of poo with money and leave it outside of a Walmart?

As we look around for the hidden camera we spot a typical Walmart customer bend over, pick up the poo encrusted dollar, shake off the bill, wipe it on her sweat pants and stick it in her pocket.
