A sales representative stops at a small manufacturing plant in the Midwest. He presents a box of cigars to the manager as a gift.

"No, thanks," says the manager. "I tried smoking a cigar once and I didn't like it." The sales rep shows his display case and then, hoping to clinch a sale, offers to take the manager out for martinis.

"No, thanks," the plant manager replies. "I tried alcohol once, but didn't like it."

Then the salesman glances out the office window and sees a golf course. "I suppose you play golf," says the salesman. "I'd like to invite you to be a guest at my club."

"No, thanks," the manager says. "I played golf once, but I didn't like it." Just then a young man enters the office. "Let me introduce my son, Bill," says the plant manager.

"Let me guess," the salesman replies. "An only child?"
