Back in the early to mid 70's when I was living with my grandparents and had grown my hair to about my belt loops, Grandpa and I went to the store one evening. Saw the ugliest looking person you ever saw. Grandpa asked him, "What happened to you?" The guy answered, "I got my ponytail caught in the lathe at work!"
Yikes
5 minutes later and several aisles over, Grandpa told me, "I ain't gonna ever tell you to get your hair cut again."Didn't have long hair very much after that.
