My worst haircut was back in about '72, my dad was rather strict in his sons getting haircuts, so it was off to the barbershop,about every 4-6 weeks. Our town had two shops, one always had a long wait, and the other shop was usually empty, one barber, so dad would drop us of there. 

On this particular Saturday the usually empty shop had another barber working along side our regular barber. As the four of us entered the shop I reluctantly took a seat in the new barbers chair, he was young, and had relatively long hair, so figured I was safe. My hair at the time was a couple of inches on the sides, down to my collar in back, and about 4-5 inches on top. He asked if I wanted a medium, not sure what that was, but it sounded longer than a regualr haircut, and with dad an earshot away, I said yes. 

The next thing I knew the steel clippers were running up the side of my head, and by the amount of hair falling to the cape and floor, I knew I was being skinned. I could instantly feel the heat of the steel clippers and the cool draft hitting my scalp. The confirmation of how severe this cut was going to be was determined by the facial expressions on my dad and brothers faces. I knew this was going to be extremely short. The top was attacked with the same vigor, followed by thinning shears. 

About that time, which was way too late, I questioned what was he doing, and he indicated he was just taking out the bulk, but leaving the length! There was no length to be had. I think I ended up with a very short Ivy league. Needless to say, my waiting brothers stayed clear of his chair, and that was the last time my dad made us go there, from then on we endured the wait at the other shop.
