that's one of my faves too. pixies are a goldmine of nonsense lyrics. where is my mind, motorway to roswell, monkey gone to heaven, etc. incidentally those are some great songs. but taken out of context those lyrics seem retarded.
what's even funnier is that king of limbs is radioheads more post rock shoegazey album than, say, hail to the thief. lyrics aren't really meant to shine on it.
