From sheer memory alone let's see if I can remember the original lines
The Gods gave you two knees, and you took an arrow to both of them. I can respect that.
The Gods gave you two hands and you use both of them for your weapon, I can respect that.
I used to be a curved sword, then I took an adventurer to the sweetroll.
I use to be an adventurer like you, then I took an arrow in the knee.Patrolling Skyrim almost makes you wish for a sweetroll in the knee.
I don't know this one

Ahh, Sweetroll armor. By Ysmir, 'tis a wonderous knee.
I don't know which set of armor it is, probably a set I haven't used yet. Is your armor made from dragonscales? What I'd do for a set like that. Might have quoted that wrong

.
So you're the new member of the Whiterun Guard. What do you do, fetch the arrows in the knees?
No idea, I'm guess it's the Imperial Legion, haven't done that quest line yet, did storm cloaks first time around.
Knee might get nervous, a sweetroll approaches with its arrow drawn
A guard might get nervous, a man/woman approaches with his/her weapon drawn
Disrespect the sweetrolls and you disrespect me
Disrespect the law and you disrespect me... I already disrespect him, but I'm not sure I disrespect the law.
Used to be the greatest soldier in the Stormcloak army, then I took a sweetroll to the chest.
I'm guessing this is just another play on an arrow in the knee =P.
When the empire surrendered to the sweetrools, they shamed us all!
When the empire surrendered to the aldmeri/elves/thalmor, they shamed us all!
