I was playing the Pitt about two hours ago. I was sneaking around uptown after
, picking off Pitt Raiders. I rounded a corner and was confronted by three assault rifle toting raiders, who blanketed me with lead. As my dieing moments were played in slow motion, I swear one of them said "Sit!". I laughed so hard I had to pause the game after it had reloaded. Anyone who played Kingpin on Hogies' server back in the day can relate... yes, I remember you Sephiroth.
Also, I agree that the Super Mutants have the most comical lines, both quantity-wise and quality-wise. I like sneaking up on groups of them and just listening to their conversations.
