Inner monologues/conversations/thoughts are an often used device in sitcoms to address things in a more narrative state, and to open the door to an unlimited usage of cheap humor without any guidelines of maturity or rules. They are easy to use and often successful, but tonight Two and a Half Men used them in bunches to drive an entire episode. Innovative, different, but luckily it worked.
While I still find Chelsea terrible, at least we had a good-looking, and talented actress in Tricia Helfer on the show to almost outweigh her presence. Her role was predictable and uneventful, but it helped bring out the best in Alan with his misinterpretation of her not wanting him to have her phone number.
Luckily Jake was kept to a minimum tonight as well. Very funny episode, one of the best this season.
