You should never make jokes about vaginas...
Period.
The other night I was having sex with my wife when my cell phone rang. I answered it and said: "Can I call you back? I'm in the tub."
And that's when the fight started...
Guy walks into a bar and sees a dog lying in the corner licking its balls. The guy looks at the bartender and says: "Man I whish I could do that!"
The bartender tells him: "Better try petting him first!"
I saw my wife bought one of those new Wonder Bras.
Goofing around I told her: "You know why they call it the Wonder Bra? When you take it off you wonder where your tits went."
