Paul Simon is a genius. No question about it.
Also, I don't get the Radiohead video.
Instead of a distracting visual, they force you to stare at Yorke (creepy enough!) who proceeds to inflict (or have inflicted) water torture on himself while you watch. It's entirely conceptual, and reflects the song (and the album's) take on modern society, as isolating, suffocating, and confining.
