There is that stereotype of a nerd with the high pants and pocket protector and that kind of thing. That can sustain comedy for maybe a movie - hence the 'Revenge of the Nerds' franchise - but not for hopefully years on the air. It's a sight gag, not a story.
When we're dealing with the people in our family - no matter how annoying or gross they may be, no matter how self-inflicted their suffering may appear, no matter how afflicted they are with ignorance, prejudice or nose hairs - we give from the deepest parts of ourselves.
No one is immune from addiction; it afflicts people of all ages, races, classes, and professions.
