I think you’re missing the point of these shows and that’s okay.
The characters aren’t role models, they are your intrusive thoughts manifest. If you didn’t hear someone’s name when they told you, any rational person would just say it was loud and they didn’t hear you. They wouldnt go through lengths of introducing friends, finding out childhood taunts and rifling through your belongings in an attempt to save face.
The joke is in the breaking of social norms. A show about people being polite to each other doesn’t make for very good comedy.
