PHC is always about those OTHER midwesterners, not us. You know, those ones who put too much mayonnaise in everything and think all their children are above average. Not like us. They’re the funny ones, and it’s funny because it’s true…about them. Not us. Got it? We’re not like that, no sirree, but SOME midwesterners sure are!

Also, if you are a true midwesterner, you have family members who wouldn’t get the jokes in PHC.
It reminds me of a PHC sketch about how good some pasta was, with fresh basil, grated Parmigiano-Reggiano, and just a drizzle of good-quality extra virgin olive oil … And the Minnesotan lady says to the Minnesotan guy “Not bad.”
I have relatives that, before I tried to explain to them why this was funny, I would have to explain to them why pasta with fresh basil, and real parmesan, and good olive oil is good, in a way that truly transcends any type of noodle hotdish. Then I would have to explain why “Not bad” was a funny response … I think some of my family would tune that in and think Garrison Keillor was running a cooking show segment.
To contrast with a WYK feature, consider Thanks for the Memos. I know that has had me laughing out loud from time to time. But that’s about the foibles of people in power, either back at Corporate or some midwesterner gotten too big for his britches, making some ridiculous edict to the salt of the earth regular folks. It’s a down-home “we know that’s not going to work.”
In each case it’s a “they don’t get it ha ha,” but the *them * and the *us * are different.
I think this may also explain why PHC is the bigger hit. It pays better to be funny to New Yorkers and Californians.
Whew - that’s way too much deconstruction of midwestern humor. Obviously your laughtrack mileage may vary.
