They have a "family drink" called a flaming Dr. Pepper, which only halfway fits to their personalities. The "flaming" part of those drinks fit very well, as most of the family members (if not all) are of a homosexual nature. This drink is fairly strong which does not describe the family in any way. It is assumed that this drink was chosen so the family could seem cooler then they are or ever hope to be.
