I rarely see sporting events on TV, maybe once a year; and I almost never attend them live. I did see the Super Bowl on TV this year, when I was visiting my dad in his nursing home. So, I don't really understand the whole thing. I joked in the other thread about Raggytash's disdain for "inappropriately dressed young girls." But in my heart of hearts, I know Raggytash is right.
In U.S. sports, professional football and basketball teams have teams of professional dancer/cheerleaders - and many of them also appear on the pages of Playboy Magazine. College teams tone it down quite a bit. College cheerleaders are often more gymnastic and less sexual in their performances.
U.S. baseball teams don't seem to have cheerleaders, but I did get a kick out of the cheerleading squad in the bleachers at a San Francisco Giants game at the old Candlestick Park. They were all shirtless males, not necessarily in prime physical condition, each with a single letter in black shoe polish on his belly. When they sat in the right order, they spelled out G-I-A-N-T-S. They were some of the most enthusiastic cheerleaders I've ever seen.
