Summary: Monica dates a new guy named Alan and is reluctant to show him to her friends. But when she does they all love him. Phoebe keeps getting bonuses from her bank and feels guilty about it. Chandler starts smoking again.
The Good: This was another very good episode. There were more funny moments in this episode, though the episode did border on too over-the-top at times (see: The Bad). The highlights was definitely the Chandler smoking storyline. There were loads of great gags and it let Chandler give some really great lines throughout the episode. I particularly liked the scenes with Chandler smoking in his office and Chandler making the friends argue amongst themselves. The Alan story did give off some nice laughs too and there was a good use of irony with it. Lastly, I enjoyed Phoebe's story as it gives her some good development so we can begin to understand her more. Plus it was fun to see a lot of "bad" luck going her way, culminating with the big laugh with the titular thumb. The overall dialogue through the storylines was superb.
The Bad: Alan was a little unbelievable. It's really implausible that all of the friends would like him more than Monica and though it was funny, I still couldn't properly buy into it and enjoy the storyline. The laughs did feel a little less in that story too and it was honestly probably the worst we have seen from the show so far.
Best Moment: Chandler starting an argument between the friends. Hilarious and smart storytelling with very satisfying laughs.
Character of the Episode: Chandler.
Conclusion: Another really good episode, though the Alan stuff wasn't very enjoyable.
Just a high school student who loves to watch TV. And criticize it like hell.
