C'mon, Mike. You have a peep hole in your door for a reason. After watching him open the door without checking who was there twice already in the same episode, I knew it was going to be Rachel at the end and that he was going to open the door without looking again. I even yelled "Look through the peep hole, you moron!" in my head. But no, the writers were determined to make Mike be an idiot. Naked, hot chick in your bed = "Don't answer the door". I had actually gotten to like and sympathize with Louis in the last five or six episodes. He was a total a-hole in this one and now I'm back to hating him. I'll throw my shoe at the tv if Rachel EVER give Mike the time of day again.
