Austin, with all due respect to your sense of what is humorous, I think you should allow for the fact that others may be sensitive to certain elements of humor that you may not be.
I will illustrate, but we must begin by isolating a common element in different kinds of humor. There is more than one common element, but I think in every kind of humor there is a kernel of dissonance between what is expected and what actually happens/is said. This kind of dissonance is the soul of dry wit, satire, and other forms of irony. It's why accidents are funny (if no one gets hurt.) It's why most jokes are funny, and why they are no longer funny if you've heard Jordan tell it three times. (Of course, this theory of funniness doesn't explain why we all rock with laughter right along with him as he desperately tries to attain the punch line while he is gasping with laughter...)
You, Austin, have a keen sense of humor. But that does not mean that you are always "in tune" to the point that you can discern the dissonance. For instance, did you know that the music in Veggie Tales provides a hugely dissonant (and funny) element to many of the songs? Not ROFL funny but enough to make me chuckle the first time I heard them, and smile on subsequent occasions. The first one that comes to mind is "The Stuff Mart Song." This is an ad or "jingle" for Stuff Mart, and the lyrics are repetitive and silly in a way that mocks many radio jingles. That is kind of funny by itself. But it is written to the tune of the Blue Danube waltz, a lovely classical piece, and the juxtaposition of the inane lyrics and the melody is actually the funniest part of the song. Many of the Veggie songs incorporate gorgeous classical pieces, which not only display the above-average musical ability of the song writers, but also showcase a very dry wit. Not to go on and on, but "The Dance of the Cucumber" is a good example. I can't put my finger on the origins of the melody, but it is both familiar and beautiful. As a Veggie sings the words in Spanish, you expect the translation to match the soulful tune and tone of the singer. But no. It's something about a tomato looking funny in a sombrero, and then it turns violent. Again, not hysterical, but it makes me smile every time.
I ask you, are there so many smile-instigators in the world that we can sneer at one because it is not sophisticated enough? Especially when the sophistication is actually just not in the radar of some people? This is not to say their radar is defective, just on a different wavelength. Forgive me if I mixed a metaphor - I don't know enough about radar (radars, radii) to know if I did or not.
That said, "The Cheeseburger Song" is funny because of a diffent humor element - mockery. I won't take time to go into this one. Then there is the essential element of truth that makes so many things hysterically funny. Somebody summed it up well: "In every joke there is a particle of joke." This one is why my favorite joke this year pertained to Fundamentalists...
Keep smilin', friend.
