The 16-year-old, who hasn't been named, decided to have a bash at his home in Ingolstadt, southern Germany, while his parents were on holiday.
The place got trashed and the idea of tidying up was clearly too much for him.
He decided to call the police, claiming there had been a break-in.
Officers found a load of mess.
They also found out that nothing had been stolen.
They thought there was something fishy about the boy's story and gave him a grilling.
He eventually admitted that he had made the whole thing up.
Now he could be in trouble for faking a crime.
And if that's not bad enough, he's got to face up to his parents too!
