A man and woman go out, on a first date, to a drive-in movie theater.
Halfway through the movie, the man looks over and sees his date is bored to tears. He tries everything to make date a little better....asking her if she wants something from the concession stand, if she's too cold, too warm, etc....everything he tries is met with a cold, blunt response.
After about 20 minutes of trying to kill her with kindness, she tells him, "you're just fucking boring, all right?
The man says, "Well, if you're bored, I know what we can do.
She says, "What"?
He says, "Well...you can give me head.
The woman gets a strange look on her face and says, "How will that be fun for me"?
The guy looks at her and says, "Well, just before I cum in your mouth, I'll stop punching you in the head".
(My favorite all-time joke).
