Anthony Lentjes wasn t too concerned when his friend and another man started placing bets over what type of ammunition German soldiers used in their Luger handguns during WWII.
His friend Jarrod Frank claimed to have one answer, but another man - Scott Bury - said he knew the answer was 9mm because he d once robbed a bank with that gun and that s what he d used.
The bets started with $100 and may have reached $500 at one point - before the knives came out.
