I've often been asked about how much I know about insanity. This usually occurs just after I've shown someone my cartoons for the first time.
Funnily enough, I did once train to be a psychologist many years back, but I found that people boring me with their pathetic problems wasn't for me, so I didn't go back for the second day of training. Having experience of being a psychologist for even a short time did equip me with the knowledge to read people quite well, particularly insane people, of which there is many of them on the estate that I live.
The insane people are usually the ones wearing the inappropriate hats, so it's easy to spot an insane person, unless they are not wearing a hat in which case it's usually a little harder. Just asking someone if they are insane isn't usually that effective, particularly if they are Geordies, as they are likely to reply "Yeah, I'm mad me!". Playing word association games with strangers at a bus stop isn't that advisable either, as it can usually involve a discussion with the constabulary.
Concentrating just on the obvious ones with the inappropriate hats is usually the best tactic when trying to identify insane people.
So just what is an inappropriate hat you may ask? Well, wearing a bowler hat in a working mans club is obviously a clear sign of madness, unless they are part of the entertainment.
Wearing a rain hat in a charity shop can be a sign of insanity, unless the string is wet and stuck, and it has been raining outside.
Wearing a flat cap while driving an Italian supermini is a sign of insanity, unless the person is in Yorkshire at the time, in which case it's probably just a sign of poverty.
Without knowing for certain if someone is insane or not, can make it very difficult to mock and laugh at the insane people on your local estate. It's a mind-field for certain, but get it right, and there's lots of fun to be had. Basic knowledge of first aid is always useful when laughing at insanity.
