I have been a huge fan of the sitcom, and own the DVD's of seasons one and two. However, I found this episode far below par and am convinced that it was rushed to air. Jake could have phoned-in his performance, it was that lackluster. The episode premise, assumes that Alan has had his head in the sand for the last 4 years and learned nothing about women. It is also hard to believe that Charlie would have pushed the situation with the mother to the point that she used pepper spray. He's too savvy for that.
And, the rehash of the front door set of Alan's ex's house was cheesy.
