i liked "We Suck Young Blood" a ton when the album first came out and even put it on the_preppy's mix, but now (after putting the album away and taking it out again several times) I think it's one of the worst songs on the album (still a great song, though).
2+2=5 is great, also...heck, all of them are. I try not to pay too close attention to Radiohead's lyrics because they tend to take away from the music so I didn't notice all the Bush bashing, but after a few more listens I'll start remembering the lyrics, probably.
