Vote these guys in for the Darwin Awards. A crack pot team of counterfeiters sent a jammed printer in for repair. One thing, they forget to take out the counterfeit bill that was jamming the very machine they used to make the bills. The team was later busted after a 3 month investigation by the Secret Service.
Apparently, they created the fake bills, and then used them to purchase goods at Walmart (big surprise) and later returned them for real greenbacks. The cashiers that were accepting the bills were also part of the team.
The ring of counterfeiters produced over $160k in bills, most of which supposedly got into circulation.
