Anyway back to the topic ...
Here is another one:
When you save
Barcus Wroot, he acuses you either from wanting to rob him ... or (if you are Drow) of wanting to Enslave him ...
Just a single reaction later, he also sais that "ignorance is alive and well i see, deep gnomes are not restricted to the Underdark you know"
I would love to be able to tell him something like: "Excuse me?! You are the one to talk, you just acused me from being thief/slaver seconds ago!"
Then it would be awesome if conversation could be prolonged by few more sentences just for the joke:
Barcus Wroot: "Yeah ... i gues i own you an apology ... that was rude of me, sorry."
Tav: [1] "Its okey."
[2] "Good ... now give me all your valuables! / [Drow] Good ... now, on your knees, slave!"
Barcus Wroot: *shocked* "What?"
Tav: [1] "Just kidding ... have nice travel."
[2] *attack*
