I'm sure you do. But try this test. Imagine yourself as a child reading it. Would you still think it was funny, even if you didn't get it, like Bloom County?

The pleasure and humor (if one can call it that) which comes from 'Mallard Fillmore' is exclusively recognition humor. A person looks at it thinks; "Say, that's exactly what I think. That's showing them."

It's the ultimate nod to recognition humor that Vinth found it on Boortz and I'd wager linked the image directlty from there.
