Alright I've been a bit slow on the "Random Order Thread" so I'm in the progress of catching up
I find myself agreeing with this person from 10 years ago.
It had a nice beginning, but after that it dragged.
I agree about the Robot Mafia, they didn't add anything to the episode.
The best part was Zoidberg's slinky 
So the 1st act was the best. What made it good was the really funny launch sequence and The Professor saying that Bender was making all the straight people bent. It was great seeing Flexo again I just really like his voice actor I hope we see more of him in future episodes.
The 2nd act was kinda lame I mean we've had the "impersonation plot and trying to ruin the other twins/persons life" a thousand times before this is nothing new apart from a slight sci-fi twist.
The Robot Mafia was just boring and they didn't add much element to the episode at all other than getting Flexo squashed in the "Which one do I kill" type gag.
And there's two plot holes.
How did the Mafia know where Bender would be going and how did they get there first?
And how did Angelyne get there after Bender drove off without her?
Both may have reasonable exploitation's but I'm probably to stupid to figure them out.
At the end I didn't give a crap about Bender losing he as he was being more of a jerk than usual.
The Professor being bent felt a bit short.
Why would the crew want the Professor to be straight (lol) when he was so happy bent. I mean he usually sends them on life threatening missions but now he's so distracted so why would Fry and Leela give a shit!?
This is one of the worst Bender centered episodes I have seen and I give it a
7/10Edit: Wow I did not intend to write that much
