I'm busy replaying Baldur's Gate 2, and pretty much anything Minsc says makes me think of this thread. (Someone mentioned "anything by Minsc" earlier.) Unfortunately, I don't stop to write down the things he says, leaving me with no examples to give. Until I found BG's Wikiquote page...
Minsc wrote:Butt kicking for goodness!
Feel the burning stare of my HAMSTER and change your ways!
Shall we go? The butts of evil await my bootprint!
What? Boo is outraged! See his fury! It's small, so look close. Trust me, it's there.
My anger is under complete control ! COMPLETE ! I'll control it as I rip limb from limb, I WILL control it as I pound head after head!
Heh. Whatever party I build, it always has Minsc in it. How could one not
keep the gloriously demented fellow around?
