Mine is a banter between Tali and Garrus can’t recall it but it is along the kines of something with immune systems and Tali threatens with her shotgun

"Mordin wasn't my only source in STG. Or did you think I was as dumb as my brother, Wreav? What have you done?"

@KristianwithK damn I definitely need to play the Citadel DLC because I haven't played it.

@Lethal blade00 yes that made me laugh when Tali threatens Garrus with her shotgun. And to think that they make out in Mass Effect 3, only if you're not romancing Tali.

Yeah the Citadel DLC is a goldmine for funny quotes, you gotta play it, you won't regret it.

@Kiadony Yea. I just downloaded the Legendary Edition for PS4 so I can play the DLCs there because I've beaten Mass Effect 3 in both Xbox 360 and PS3 but I didn't buy the DLCs.

As for my favorite quotes, there are many (for example basically everything Javik says or, in context, Tali telling Legion that he/it does have a soul), but one of the best I often think of is this from Eve/Bakara:

"There is no reason to exist other than the hope that the next day will bring change. And if it doesn't, there is always the next."

I even have it screencapped for reference cause I just feel it too much heh.

@Kiadony very true
