What can the static from a CRT do to your skin?
This may seem like an odd thread, but I'm giving it a shot.
Every since I started messin' with TVs I noticed that if you run your hand along the face of a powered crt, your skin kind of 'absorbs' the static and then your hand has a strange scent to it, as if the static energy messed with your hand. I know this sounds absurd, but the smell is always the same no matter what type of set it is. I got to thinking  , could there be some sort of detrimental side effects to the skin from this static?

The "scent" you're talking about is Ozone, generated by the static discharges between the tube face and your hand, and is absolutely harmless.
But, if you touch anything connected to the set's chassis ground with your hands while touching the charged screen with another part of your body (this may happen when you carry a tabletop set with your chest against the screen) your body will provide a quick discharge path from the screen to the chassis and you'll get a beefy shock, i once dropped a set this way

Ozone used to be created in large banks to help keep the tellers alert while counting large sums of money. it is chemically just an Oxygen molecule with an extra electron. O3

Being bit of a practical joker, I've gathered up a fair amount of charge off some TV sets we had in the lab. Was wearing rubber sneakers, so i was well insulated. Was in a part of the lab where to get out you had to squeeze past my coworker who was at a computer. Waited until he was done typing on the keyboard. Then squeezed past him. I discharged to him, from my leg to his ass...
He was from Hong Kong, an area usually humid and thus he wasn't used to static discharge. He  me...

I had a teacher in fifth grade who was into conspiracy theories and all that sort of thing. He told the class one day to try this: hold your arm up to the TV screen and change the channel; you will feel the charge. He told us that was a burst of radiation being sent into our arm and that, once in, it could never leave. This guy also taught us sex ed! If I'm warped, perhaps that explains it. (guy is also a distant cousin of mine...)

When i was a kid i had a 1920s phone crank generator, you could easily get over 300 volts AC out of that thing.
Well, i once had an eye flickering, muscle convulsing challenge with my friends using the output from that thing, it's really hard to get past the 5 second mark, the damn thing makes you scream for your mom
