You know the sort of thing.... those undocumented little things that are put in as a joke, or a tribute to some person or other.
Or maybe an item or NPC that is a 'shout out' to another game, or movie or book?
Let's make a list of those Easter Eggs that Bethesda traditionally put in their games
[SPOILERS LIKELY]
Its not really a special item, but i was delighted to find a copy of 'the lusty argonian maid v3', this is surely bethesdas response to all the mirthful feedback from fans of the series.
Also, lucien lachances occasional comment 'i feel a disturbance in the void' and the fact that his apparation is so similar to a ghost jedi made me laugh a little. '...disturbance in the force'
There is a sword in the stone mate, but its sadly found randomly just outside a dungeon, i was there last night. If it was me i would have placed it at the bottom of a cryt with impressive god-rays shining down on it for extra awe. Oh, and it wouldnt be made out of crappy iron. I would have given it amazing enchantments and had it so it couldnt be removed by the player for some nice in-game frustration.
Dont know why the half-assed it and used an item picked up in the first room of the game.
I heard an easter egg in the form of a conversation between Calcelmo and his nephew in Markarth keep. It was yet another starwars easter egg where Calcelmo was telling his nephew," next time for sure" and that he "needed him" this was copying the beginning of star wars a new hope when luke wants to leave and join the rebellion. I dont know how many times this will happen, I have only heard it once, despite trying to wait an listen.
Temba Wide-Arm, an NPC female located at the saw mill in the town below High Hrothgar. She gives the Grin and Bear It quest. I think this may possibly be a reference to Star Trek TNG episode where an alien speaking in metaphors, says 'Temba, his arms wide' several times, once when offering to share his fire with Picard (yes, I'm a trekkie - but I didn't care too much for that particular episode). I think they should've made Temba Wide-Arm male.
I also found the skeletal hand holding a sword in a lake, but this has been mentioned on this post already. Coincidently?, the Lady Stone is found in a lake.
