[Rune Son of Bjarne]

I find that the problem is that none of these things are really absurd in essence, sure you can argue that Denethor did some absurd things in his latter days, but that is pretty much the extend of it. It is only Bombadil where you can make a proper case of the very character being a bit of an absurdity (though very competent in his own right).

I guess you could take the Legolas skateboarding and other antics and pin the absurd label on that. You could even claim that it is absurd that a man as gifted as Tolkien could not make the Legolas character work, but all of this seems a tad vague.
