If you haven't seen when aliens attack, don't read it.
Well the basic premise is, Fry's sloth and knowledge of the 20th century save the world. Hmm, I haven't seen that since the garbage ball episode . . . Other than that, I thought the episode was good. Anyway, here are some bits and references that I noticed. I've tried to remove the ones that I have seen posted here already.
Beer spilling on control board from "Sat. Night Live" parody of "The China Syndrome", "The Pepsi Syndrome".
The aliens had a mouse (or whatever) hole in their living room.
The evil governor of NY from the 2600's looks one of the villains in "The Tick".
Leela is once again bothered when Fry show's dis-interest.
The Statue of Liberty is not being used for the tube transport system as it was in the first episode.
The super advanced aliens are using a late 50's style microphone.
During Zap's pep talk, someone is wearing a "Moon U" T-shirt.
The "Hubble Telescope" looked just like the alien mothership, only smaller.
Leela with the extra eye on the side of her head looks like that famous Picasso painting I don't know the name of.
Zoidberg is once again blamed for something he didn't do.
During the hugging sequence after the aliens leave we see: The street is right in front of "Sparky's Den", note the clock. The guy who climbs on the clock looks like Ignor. The robot who said "That equals true" at Benders Baptism. One of the robots that was "jacking on" when Bender arrived at the party. Hooker-bot 5000 The clown that hugs the Nun looks like Krusty with a hair cut.
