I don't really follow comedians but I watched Robin Williams's "Good Morning Vietnam" awhile back and it struck me that his rapid-fire patter was taken straight from the book of Danny Kaye.
As to all those activities, other than the swimming, I guess I would wonder what I would (ahem) do with myself. But I'm sure it all gets worked out somehow.
Ugly people should not go to these places. That is why I never went back. Too many saggy, disgusting people.
The time we went, we went up to a group of "healthy looking" girls and said "hello", as I often did in my teenage days. They were very friendly, and why wouldn't they be? I was 155 pounds with 6% body fat and model-like looks.
