When you bring Cole with you to the augur in Jaws of Hakkon - the augur summons a bunch of spirits. Cole: "Hello! :D"
He sounds so fundamentally happy haha 
And of course, all banter between Zevran and Ohgren.
Oghren: Elf!
Zevran: Oghren!
Oghren: I have something to say to you!
Zevran: I am all ears, as we elves like to say.
Oghren: I... Well, now I forgot.
Zevran: Alas.
Oghren: But just know I had something.
Zevran: You've had several somethings, I suspect. It's part of your charm.
Zevran: I think I have a joke for you, my fine dwarven friend.
Oghren: Just don't expect me to laugh.
Zevran: So a human, an elf, and a dwarf are walking down a trail beside a stream, and they stop to take a ******.
Oghren: All right. Things are lookin' up. Continue.
Zevran: After, the human takes out some soap and begins washing his hands. "We humans have learned how to be clean and hygienic," he says to the others. The elf begins picking some leaves off the trees and wipes his hands with them. "We elves do as tradition has taught us and use what nature has provided." The dwarf, meanwhile, has pulled up his trousers and is already on his way down the trail. "And our ancestors," he calls back, "taught us dwarves not to ****** on our hands!" (Laughs)
Oghren: Heh. Shows you what you know about dwarves.
Oghren: Hey, elf. You're all right.
Zevran: Am I?
Oghren: Aye. I was thinking, I was thinking that you're... you're just all right.
Zevran: Drunk again, Oghren?
Oghren: "Drunk again, Oghren?" You sound like my father. He was all, "You're drunk; stop wetting on the table."
Zevran: How dare he.
Oghren: Least my mom had the good sense to hide the booze from him. So, you know, she could drink where he couldn't see her. (Laughs)
Zevran: That's heartwarming.
Oghren: Hey buddy, let's not go crazy or anything. Keep your pants where I can see 'em.
