>Hey Keanu you wanna come over to my house and fuck my wife? She's a big fan of yours
>If you don't like brunettes I'll even throw in a blonde for free
>In fact, let's turn it into a movie! I'll call it "Knock Knock"
>when the other chick in your movie is hotter than your wife
>when you're shooting on location 5,000 miles away and thinking your wife won't fuck the pool boy for the 8 weeks you're not in the country
