When Bender is telling the bees "I didn't mean you're all fat", he doesn't speak in the bee language.
Kug "him do good snu-snu" about Fry, but she actually did snu-snu with Zapp Brannigan.
In another episode, Fry is delivering a package to an Amazonian who looks a lot like Kug, then crashed the ship shortly after. It is possible that was Kug and they did snu-snu afterwards.
In this episode, the old crew is revealed to have been killed by the space bees, while the packet containing their career chips in the pilot episode was marked "Contents of Space Wasp's Stomach." Still, it's pretty close.
When the crew enters the Planet Express ship after collecting the honey from the hive, Fry's hair is messy. When he tells Leela "Look out!", his hair is normal. When Fry tried to protect Leela and gets impaled by the stinger, his hair is messy again.
After Zoidberg says "I only wish I could have removed the singer", the angle changes and Fry's burned time card is gone.
When Fry gets impaled with the stinger, it goes into him at a downward angle and leaves facing up. The stinger faces the same way at his funeral, but when the clergyman is describing his death, the stinger is rotated. This could however be due to Leela's dream being unrealistic.
