Gas!
A 75 year old man in the UK got the shock of his life when police arrived at his door at the weekend.
Colin Mitchell from St Albans was even more stunned when they told him they were investigating a claim of "offensive human noises".
His neighbour had reported him for excessive farting but the great-grandad knew the source and it wasn't his bottom!
No, it was a child's toy that simulated fart noises and it was being played by Colin's great-grandson.
The officers were as baffled as the pensioner.
Colin told South West News Service:
"What an absolute waste of police time. They came to my door because Charlie was playing with a fart toy."
"The police do an amazing job but it is ridiculous when they don't have the manpower or money that someone can call them out for such a stupid job."
