I agree with Santoka, I mostly like the ones that are more subtle.
I recently discovered some easter eggs that I didn't know of when looking at the wiki (
http://fallout.wikia.com/wiki/Fallout_2_cultural_references ), a lot of them I didn't even notice in the game and now that I read them I find them quite hillarious

Bill Clinton
When you reach the Enclave Oil Rig, go to president's chambers. You'll find his secretary that speaks as Monica. About the dress and... well, you know what. [/spoiler:16fd8f7daa]
[spoiler:16fd8f7daa]Funny Farm
(It starred Chevy Chase) - In the town of Modoc when you go to Rose's Bed & Breakfast, you can enter into the Brahmin Fry Eating Contest. Right as you break the record, you learn that the Brahmin Fries are actually Brahmin testicles. In the movie "Funny Farm", Chevy Chase enters a Lamb Fry Eating Contest and his reaction (when he learns that they are sheep testicles) to it is identical to your character's in the game.

[spoiler:16fd8f7daa]Goodfellas
Flick in the Den says the following line: "You think I'm some kinda clown? Am I here to amuse you, is that it?". This is a direct reference to the scene where Joe Pesci is talking to Ray Liotta in the gangster movie Goodfellas by Martin Scorsese. [/spoiler:16fd8f7daa]

Pocahontas
Sometimes, a prostitute will say "You were great in Pokeahotass."

Wizard of Oz, The
In the Northern California Republic, you'll come across a girl and her robot standing outside of a building. The girl's name is Dorothy, and her trusty robot who follows her everywhere is Toto.
In the Special encounter The Tin Man, the player encounters someone standing, rigid and unmoving, in power armor, saying repeatedly, "Oil can". When the player uses a nearby Oil Can on the figure's armor, the Tin Man walks away, after gifting the player with a Micro Fusion Cell.
If you are wearing Power Armor, a prostitute may make the following comment: "Look, Tin Man, if you want me to dress up as Dorothy or Toto, that's extra." [/spoiler:16fd8f7daa]
I also like the references on the grave stones a lot
