We all make mistakes. Some, bigger than others. This German bank teller made a big mistake. A really big mistake.

Apparently, he was supposed to be transferring around $85 from one account to another. It would seem that he didn't sleep well the night before though, and fell asleep on his keyboard, causing the "2" key to be pressed down.

Instead of transferring the $85, he transferred around $295 million.

Oops

A question that I get a lot is, "do you ever mess up on the radio?" The answer is a resounding, yes. Every day. Hopefully though, most people don't notice. And it certainly isn't a $210 million mistake.

So what's the biggest mistake you've ever made at work? Tell us in the comments section!
