That's really dark
Not sure if this guy counts as a weirdo... but when I was at school, there was a guy we dubbed the 'Professor' with full white beard and scruffy hair. He used to stand outside our school everyday simply writing down the number plates of passing cars for most of the day, bear in mind this was before the days of paedogeddon, and if anyone approached him they were promptly shouted at and spat on, he even hit a kid once with his cane, but still kept coming back time after time...
We later learnt his wife and daughter had been killed in a hit and run accident on that very road several years ago and no one had ever been brought to justice. He was eventually stuck in our local mental hospital :/
