"Beach" joke

Goldie, a recently widowed older Jewish lady, was sitting on a Florida beach near Seven Springs. She looked up and noticed that an elderly gentleman had walked up, placed his blanket on the sand nearby, and began reading a book. Smiling, she attempted to strike up a conversation with him.
"Hello, sir, how are you?"
"Fine, thank you," he responded, and turned back to his book.
"I love the beach. Do you come here often?" she asked.
"First time since my wife passed away last year," he replied.
"Do you live around here?" she asked.
"Yes," he answered, continuing to read.
Goldie persisted. "Do you like pussy cats?"
With that, he threw his book down, jumped off his blanket onto hers, tore off both their swimsuits and gave her the most passionate ride of her life. As the cloud of sand began to settle, Goldie gasped and asked the man,
"How did you know that was what I wanted?"
The man replied, "How did you know my name was Katz?"
