A German man has filed fraud charges when he realized that he had paid 40 euro cents ($0.55) more than he expected for a call-in television quiz show. The quiz was “How much milk do 10 oxen produce in 10 minutes if five oxen produce five litres in five minutes?” The man devised a formula to answer the question and went to a pay phone and made a call which he expected to be a 50 cents call.

He was angered when the cost came to 90 cents. And the funniest part is the phone-in show said the question has no answer because it is a riddle, this made him even more incensed.

The man did not feel funny at all, he filed a fraud charge at a police station at 3 a.m.
