There was this guy who took very good care of his body. He lifted weights and jogged 20km a day. One morning, he looked in the mirror to admire his body. He noticed that his body was sun-tanned all over, with the exception of his penis, which he decided to do something about.
That afternoon, he went to the beach, got completely undressed and buried himself in the sand - except for his old chap. Two old ladies came striding along the beach. Upon seeing the man's old fella sticking out of the sand, one of them began to move it around with her cane.
She remarked to the other "There really is no justice in the world".
The other lady said "What do you mean?"
The first old lady said "When I was 20, I was curious about it. When I was 30, I enjoyed it. When I was 40, I pleaded for it. When I was 50, I even paid for it. When I was 60, I prayed for it. When I was70, I forgot about it. And now that I am 80, the damn things are growing wild and my knees hurt too much to squat."
