Rollings -- We're done is a holotape in Fallout 3. It can be found in Rockopolis. It is the first mention of The Pitt, which was later featured in a Fallout 3 add-on.
That's the last of these fucking hole dwellers. Jurley wants to shop them around up north. Not sure if they'll make good slaves, since their eyesight is so shitty, but that's not our problem.
So gather the boys and saddle up.
Next stop, the Pitt!
