A man met a beautiful blonde lady and decided he wanted to marry her
right away.
She said, "But we don't know anything about each other."
He said, "That's all right, we'll learn about each other as we go along."
So she consented, they were married, and off they went on a honeymoon
at a very nice resort. One morning they were lying by the pool, when he got
up off of his towel, climbed up to the 10 metre board and did a two and a
half tuck, followed by three rotations in the pike position, at which
point he straightened out and cut the water like a knife. After a few
more demonstrations, he came back and lay down on the towel.

She said, "That was incredible!"
He said, "I used to be an Olympic diving champion. You see, I told you
we'd learn more about each other as we went along."
So she got up, jumped in the pool and started doing laps. After
seventy-five laps she climbed out of the pool, lay down on her
towel and was hardly out of breath.
He said, "That was incredible! Were you an Olympic endurance swimmer?"
"No," she said, "I was a prostitute in Liverpool but I worked both
sides of the river."
