It seems that Fry does not yet have a crush on Leela in this episode because he does not mention or hint at an attraction to her, despite all the references to her love life.
The music played at the Hip Joint is the same piece played during Fry's first visit outdoors in the future in 'Space Pilot 3000.'
How could they look to Vergon 6 after it exploded? They're heading away from the planet, and the bridge is in the front of the ship.
A greater variety of animals are seen in the Planet Express cargo hold than what was mentioned on Leela's list of animals.
Nibbler's third eye shrinks shortly after he is first introduced.
When in the 'Lovenasium,' the lever controlling Zapp's 'motorbed' disappears.
The medal Zapp displays on his chest is not worn moments earlier, but maybe this is part of the joke.
When Zapp is telling Fry about the Killbots' weakness, the left door, the door's control panel, and the controls directly behind the captain's chair look extremely different than when he says "I'll be in the escape pod." The buttons are bigger and in less quantity, the control panel is double in height, and so on. The chair also has two buttons at each side that weren't there in the previous scenes, but appear again when Leela calls him.
Zapp's chair only has the book container when he shows his 'Big Book of War;' it's not seen when he dictates his first journal, and dissapears the next time we see the chair.
During Fry's "Wow... the Zapp Brannigan?" line, Leela's seat, as well as the navigation console, are directly behind Fry, but when Fry says "Leela's got a boyfriend," it is behind him and to the right, which is the correct position.
When Zapp Brannigan predicts his "light dinner," his hand is animated to rub against his chin, but it is actually floating a few inches to the left.
The stenotype Kif uses with the first captain's journal only appears for that precise moment. In all other scenes, it is replaced by what looks like a full computer panel.
When Leela says "could you guys please stop talking about my personal life?", we see the hangar in the background, but the ship is missing.
At The Hip Joint, Amy and Leela suddenly switch places before Bolt Rollins sits down.
A small sign outside of The Hip Joint reads 'Ten Drink Minimum.'
There actually seems to be 1 of each alien animal in the Planet Express ship cargo bay, not 2, so it doesn't really matter if they all get eaten by Nibbler.
As Leela sneaks out of the 'Lovenasium,' she's holding her boots in her hand. She remains wearing only her socks for the rest of the scene.
The candles in Zapp's 'Lovenasium' are melted after the commercial break.
The outfit suggested for Leela has nothing covering the pubic area.
