I introduced one of those guys in my dream (I said he keeps on changing but he was just one guy I think) to someone I know in real life and I said, "Uh, this is Ashton Kutcher." Then I turned to him and asked, "Wait, what's your name again?"
For the record, I'm not specially smitten with Ashton Kutcher. I might have thought he was cute but I'm way way past fantasizing about cute men. I just thought this part was especially funny because I slept with one guy and when the gory, graphic, fun part was over, I realized I only knew his first name. I had to ask for his last name right after his orgasm. "Oh?" He looked puzzled. "I haven't told you?" Would I be asking if he had?
