A middle-aged woman reads that vaginas get wider and deeper with age. So she tries to check her own by stripping off, putting a mirror on the floor and spreading her legs over it.
Suddenly, her husband comes in and grabs her arm, violently pulling her away from where the mirror is laying.
“You could have broken my arm!” she shouts at him.
He points at the mirror and says “But if you’d fallen down that hole, you would have broken your neck.”
