You should never make jokes about vaginas...
Period.
Little Johnny came home and told his mom he got kicked out of mathematics class. His mom asked "What happened."
Little Johnny told her: "The teacher asked me, 'What comes after 69?' Apparently 'mouthwash' was the wrong answer!"
I just bought the latest sleep-number smart bed. It detects when you're screwing your wife, locks the front door and turns on the stereo so your neighbors can't hear you. My number is 69.
My wife came in complaining about me never lifting a finger around the house.
So I did - the middle one.
And that's when the fight started...
