AM I CRAZY ?

This morning I was sitting beside the lake, as usual, watching Britt fishing. (She never catches anything.) A road passes near the lake and I was very surprised to see a man ski-ing on the road. " I must be crazy " I thought. " It's impossible. He can't ski on a road without snow ."
"Hey Britt, " I cried. " Take me to hospital quickly. I'm going crazy in this country."
She was too busy fishing to take me to hospital, but she explained the mystery. the skis were roller-skis, which run on a lot of little rollers. They use them in the summer, for training.
