In the Alienated Episode you can hear the movie in the background. Made funnier by this being before Battle: Los Angeles was being filmed, maybe the writers were Eureka fans?
"Duck Duck Goose": In the extreme foreground as the Starks are discussing Kevin, the hand from T2 can be seen in the original glass dome. Guess who Henry played?
Let's just say that, like Stargate SG-1 before it, and even moreso since the characters are quite often huge nerds, there's no shortage of pop culture references in Eureka.
And how about that LCL (Neon Genesis Evangelion fame) that Carter is dunked in to save his life in season 2 episode "Noche de Suenos".
Fargo's time travel arrival in Founder's Day is a Shout Out to the Terminator series, complete with music.
And then in "Momstrosity" he says, "Come with me if you want to live!" And in "Crossing Over", Claudia calls him Fargonator.
He also gets in some surprisingly skilled Terminator-like stunt driving (in a hatchback in the woods no less) complete with stick shifting sequence. Who knew!?

GD Computer Mimicking Fargo's Voice: You'll never find your way out. Resistance is futile.

Glimpse starts with one to the 50's propaganda films.
Fargo: Global Dynamics wants you!
Also in Glimpse, is The Cameo for Stan Lee, who provides a Shout Out to The Hulk. He appears as Dr. Lee, specializing in the effects of gamma radiation, you can call him Generalissimo, and "Don't make me angry, you won't like me when I'm angry."
Also, Bear Mc Creary decided to play a tribute with "The Lonely Man Theme" from the Hulk TV Series playing in the background during that scene. Which was slightly adapted to resemble the "Mc Creary Eureka Theme" (the one in the credits and in the background from season 2 onward).
When Andy is instructing people on evacuation, Jo adds "You heard Mr. Data, keep it movin'..."
