This is interchangeable by sex, of course, it could just as easily be “a woman walks into a psychologist’s office”…
A guy walks into a psychiatrist’s office and sits down on the couch for his first working appointment. He looks at the psychologist and and the psychologist back at him. The psychologist says in that quiet, calm psychologist voice, let’s begin.
The guy says, “Well, my wife has a bunch of flaws that really annoy me and I’d like to know how to fix them.”
The psychologist whispers under his breath, “We’re going to need a bigger couch.”
Fans of the 1970’s Steven Spielberg classic, Jaws will get this joke. For the rest… erm, dude. It’s Jaws. You gotta see that movie.
