Bragging golfers

Four men went to play golf.
Three of them headed to the first tee and the fourth went into the clubhouse to take care of the bill.
The three men started talking and bragging about their sons.

The first man told the others, "My son is a home builder, and he is so successful he gave a friend a new home for free. Just gave it to him!"

The second man said, "My son was a car salesman, and now he owns a multi-line dealership. He's so successful that he gave one of his friends a new Mercedes, fully loaded."

The third man, not wanting to be outdone, bragged, "My son is a stockbroker, and he's doing so well that he gave his friend an entire stock and bond portfolio."

The fourth man joined them on the tee after a few minutes of taking care of business.

The first man mentioned, "We were just talking about our sons. How is yours doing?"

The fourth man replied, "Well, my son is gay and go-go dances in a gay bar."

The other three men grew silent as he continued, "I'm not totally thrilled about the dancing job, but he must be doing well. His last three boyfriends gave him a house, a new Mercedes, and a complete stock portfolio!"
