"Finding A Penis" joke

There was a little old man who really took care of his body. He lifted weights and jogged six miles every day. One morning he looked into the mirror and was admiring his body when he noticed that he was suntanned over his entire body with the exception of his penis. He decided to do something about it. So he went to the beach, undressed completely, and buried himself in the sand except for his penis.
Just then two little old ladies were strolling along the beach, one walking with a cane. Upon seeing this "thing" sticking out of the sand, she began to move it about with her cane. She remarked to the other little old lady,
"There ain't hardly no justice in this world."
The other little old lady asked, "What do you mean by that?"
"Well," the first lady said, "When I was 20, I was curious about it.
"When I was 30, I enjoyed it.
"When I was 40, I asked for it.
"When I was 50, I paid for it.
"When I was 60, I prayed for it.
"When I was 70, I forgot about it."
And now that I'm 80, the damn things are growing wild, and I'm too old to squat !"
