"Everything's for sale, my friend. Everything. If I had a sister, I'd sell her in a second." - Belethor of Whiterun
"What a curious question. Well, I enjoy moonlit nights, taking long walks on the beach, unicorns, and knitting. In fact, I once took a seaside stroll on a moonlit night, and discovered a unicorn...which I proceeded to stab in the throat with a crochet needle. I am a woman of refined, yet simple tastes." - Gabriella of the Dark Brotherhood
"In truth, I'm no more a little girl than you are. I was once, of course. Three hundred years ago. Vampirism tends to keep one remarkably... fresh." - Babette of the Dark Brotherhood
"Another wanderer, here to lick my father's boots. Good job." - Nelkir, son of Jarl Balgruuf
“Cicero will be right here. Spiders could eat my face off, faithful Cicero would not move an inch!” - Cicero of the Dark Brotherhood
“Oh! Cicero will go to Jorrvaskr and dance for the Companions! Maybe they'll...um, on second thought, maybe not.” - Cicero again, proving he has a strong sense of self-preservation
And one of my personal favorites (probably because to my twisted mind it sounds really perverted): "I'm not a man, I'm a weapon in human form. Just unsheathe me, and point me at the enemy." - Hrongar of Whiterun
