I always liked Daria's father, one of the great hapless TV fathers.

Also, Daria has two of the best quotes ever about relationships:

'I mean someone you can get along with for more than one evening. Who can share your hopes and dreams, your trials and disappointments. Someone you look forward to seeing day after day, week after week, (angrier) month after month, year after year, the same old complaints about his uncaring father. God is he ever going to get over-'

'Daria, do you ever think that maybe guys and girls aren't meant to understand each other? Like it's all part of some big unfunny joke on us that we'll be struggling with for the rest of our lives? Oh look, celery stalks.'
