Hahaha just kidding! =P
Seriously, probably the random comments on my ebony armor. I personally like the Ahnold guy. I think he was from Age of Conan, wasn't he?
I LOVE that they got that one guy from AoC to do a few lines. The guy in Riften selling Falmerblood Elixir. I always expect him to say "can you do somethin' for meh?" "Crom and Imir!" =P
Oh, and the lady who voiced Mithrelle and the brothel mistress... So awesome they got her! =)
So many others... definitely got the “power of the voice” going on!

EDIT: "Don't think you can barter with me like I'm one of those damned shopkeepers." Lol occupational envy much? =P
