One of my favorite fallout moments was in Fallout 2 with low intelligence character. If you go to Vault city and talk with one of the water vendors or something like that. The woman insults you and pretty much tells you to leave, less you hurt yourself. What ensued was pretty amusing. As the line of dialouge went something like this. "*Sniff* *sniff* "Me no like big smart mean people, Me invite clowns and ice cream and not INVITE BIG MEAN PEOPLE LIKE YOU." Another moment was with Marcus and the Cat's Paw talk. Or the intelligent rad scorpion.
