While the arrow in the knee is chucklesome, there are many quotes out there that are a lot more funny to hear about. I heard one the other day and I just stopped and laughed.
"You know, I could have gone into that Sanctuary, wiped out all those Dark Brotherhood types... But I was... Sick, that day."
I just don't know how the arrow one in particular rose to fame when there are quite a few other gems out there. The way the guards say some of their lines help too. Opinions?
