Oh bugger? How can that be anyone's favorite quote? It's quite simple right? Oh bugger!
Like Divine Avenger said anyone who has done the quest will know why it's funny.
For me it's the whole dialogue from Zagan's first line to Talana's comment at the end, which is perfectly summarized by the simple line "Oh bugger" (actually, the whole exchange revolves around that)
Wait, are you telling Divine Avenger and me what should or should not be our favorite quote? That's a bit weird, I didn't know there were guidelines for favorite quotes. I'll make sure to follow the guidelines on favorite quotes next time.

added fav dialogue:
Behrlihn saying something about banning rhyming because of Bellegar.
Yes. There are guidelines and they must be followed. Failure to abide by the rules will result in you being banned from the forums.

No, I was just curious as to why two simple words could be someone's favorite quotes in a game where the dialogue is magnificent. We have Bellegar for God's sake and he's one of the most colorful, entertaining and elaborate characters that I have met in an RPG. ALL of his dialogues have never failed to amuse me. The guy is crazy and I love him for that. Even when he's not actively in the game, his quotes (found in books or quoted by NPC's) still succeed. Whoever created Bellegar was a brilliant mad man.
As for the Oh Bugger quote. I agree that it suited the quest but can it (and what led up to it) even contend against Bellegar? No! Not even the quote (and scenario) I posted could contend. Bellegar is just brilliant and even Zandalor's dialogue from Divine Divinity can't contend.
I bet that Bellegar is rhythmic even when he's asleep.
I think I misspoke though. I can see how the Oh Bugger (and the scenario behind it) quote can be somebody's favorite quote (and it evidently is) but I should have said what I said above to avoid confusion. I think Bellegar's quotes are the best. I was thinking that Divine Avenger was putting the Oh Bugger quote above Bellegar's quotes and I mean...even Joram - and his evil twin Jorom - know that you can't do that. That's blasphemy!
Is there anyone who doesn't like Bellegar and/or his quotes so that we can burn them?
P.S
My apologies to Bellegar. I should have mentioned his quotes as being my BEST quotes in the game in the first post that I made. I believe that his dialogue is well written, only certain dialogue from Dragon Age: Origins (Alistair and Oghren) has ever had the same effect on me but I think that Bellegar remains ahead just because of how INTELLIGENT his quotes are.
It's for this reason that I'm disappointed that so many don't know of Divinity 2. The dialogue contained in it is magnificent and if only many people heard of Bellegar's quotes...I'd imagine seeing his quotes popping up on forums like memes.
P.P.S
My whole post is just a joke. Of course you can like whatever quote you want from DKS better than Bellegar's quotes. My opinion however is that his dialogues are the best lines in the game and he remains one of my favorite characters from an RPG (as I'm sure that many of you will agree).
