At first glance this premise sounds boring, generic, cliched, but it was the side storyline it created with Herb, Alan, Charlie and Jerome which was simply fantastic.
When you have a simple line like, "So, what are you guys talking about?" followed by, Masturbating in the Y." you know two things: this is Two and a Half Men and you're probably on the floor laughing.
The scenes with the four guys dropping one liners (or zings, as they were called here) is why this show was great. Not smart, British humor like you might find from a Ricky Gervais show, but just good, bad-natured, pushing the limit of network TV and the FCC jokes.
The singing at the end could have been done without, but I've grown accustomed to these stupid final scenes on the show. All in all though, an impressive episode.
