Mr. Birchum has set ups for great jokes. He's an incredibly inept and bitter man raging at a world he doesn't understand.
All in the Family milked this premise for comedic gold for 9 seasons.
The difference between the two titular characters is that Birchum isn't allowed to be wrong. A straight white alpha male being wrong about anything is WOKE. So he's always painted as being in the right and cheered for his laziness, over the top anger, and stupidity.
In the first episode he's angry that the students he teaches shop.... don't know how to build anything. That it's his job to teach them is irrelevant and criticizing or joking that he's angry at them for his own failure would be WOKE. It reminds me of the time I heard my duplex very conservative neighbor calling his 12 year old child a moron for not knowing how to set up a tent. You're just suppose to KNOW this crap and if someone has to TEACH you then you've failed. Even if you are TWELVE.
Mr. Birchum isn't designed to be funny or entertaining. It's designed to be bitter and spiteful. Because, ever since the election of a black president, that's all conservatism is now. Unending bitterness and spite. All of their supposed beliefs are just avenues to hurt the people they hate and those beliefs are abandoned the second they're no longer useful to hurt people.
