Actually, I was referring to the golf joke.
Two guys were playing golf, and were stuck behind a pair of female golfers. The two men thought they could play faster, and discussed asking to “play through”.
One of them walked forward, and then came back.
“I couldn’t go through with it. When I got closer, I realized that one of those women is my wife, and the other is my girlfriend!”
“That could be a problem. How about this? I’ll go up and ask them, and we’ll get beyond this impasse.” Then he walked forward.
He got closer, and then he too stopped, and turned back.
“Now what’s wrong?” His friend asked.
“It’s a small world.”
