"Bus driver loses mental patients" is a scary legend about a man who works for the local insane asylum and ends up accidentally allowing the inmates to escape. It is also known as "Bus Full of Mental Patients".
There was a bus driver who worked for the county hospital. One day, he was transporting 20 mental patients to the state insane asylum. On the way, he got thirsty and decided to stop for a few drinks at a bar.
When he got back to his bus, he was shocked to find it empty. The mental patients had somehow managed to get free and all of them had escaped. Worried that he would lose his job, the crafty bus driver came up with an idea.
He drove the bus down the road and pulled over at the first bus stop he found. He opened the doors and all of the people waiting there got on the bus. The bus driver took them to the insane asylum and told the staff that these patients were especially violent and had to be restrained.
It took months before the staff of the insane asylum realized their mistake. By that time, many of the people had actually gone insane. The real mental patients have still not been found.
