Riverboat

Jeff was on holiday on a riverboat casino on the Thames with his wife.

By the second day, they were already fighting.

"Your dresses are too tight," he screamed. "You look like a tramp."

"Oh," she replied, "You want to see me in something long and flowing? If you find something long and flowing, let me know and I will get in it."

So, he pushed her into the river.
