In the quest "Those!", after you and Brian Wilks arrive in Grayditch, he will tell you about his father and where his home is (other things may be asked though). After you agree to check if his father is alive, Brian will go into one of the radiation preservation shelters. When he enters, sooner or later the phrase "Now I know what a TV dinner feels like" can be heard. This is a reference to a line Bruce Willis mutters when he is crawling through an air conditioning vent in one of the Die Hard movies.
