One of the worst offerings of this show I have ever seen. The plot wore thin, and it just wasn't memorable at all. The writing was absolutely atrocious. Alan masturbating throughout the whole episode was definitely not humorous, it just got annoying after a while, something that was never funny in the first place.
Charlie's plot is nothing we haven't seen before. Charlie overreacts to his date being 4 years older than him? Then he becomes attracted to the woman's daughter who is 20, and a porn star? Just a very unoriginal plot, that went to tolerable to absolutely ridiculous.
Jon Cryer and Charlie Sheen don't even look like they're trying anymore, this was obviously one of the worst of the series.
