I was visiting someone a couple years ago who had a huge TV in their family room and they asked me if I ever watch Youtube on the TV screen and I said no, my internet service is so slow I don't even have it hooked up to a TV. So anyway, they started pulling up some of their favorite Youtube videos and had several showing people popping pimples and squeezing black heads. They thought some of the best were on their back and a lot of people were heating a small glass and somehow using that to get it to come out or whatever. I'm not sure as the whole thing sickened me so much I got up to head for their back yard so they changed it to cute little kittens and puppies playing.
