Oh Merry -
I remember the injection gun - to me that was truly barbaric! I was a 65# kid, getting vaccines in the school cafeteria with hundreds of others. A very large lady wrapped her arms around me and smashed me into her bosom. The nurse jammed the gun against my arm and shot me. It hurt like bloody %&*#@ and I had a swollen bruised arm for 6 weeks - which all the kids delighted in punching every day in the halls. After that, my Mom refused to let any of us 6 kids have our shots that way (as the oldest, I was the guinea pig.)
