The really busy part was changing my bedsheet. I decided to rotate the mattress as well; so I pulled off the old bedsheet and the egg-carton foam pad (makes for comfy sleepin'), rotated the mattress 180 degrees around a vertical axis, then put the pad back and put the new bedsheet on. All this to the music of the Beatles' "Help!" album.
Speaking of which, I was always confused by the cover of "Help!"... according to one book I read, the Beatles are spelling out "HELP" in semaphore with their arms. Except that they're not. It looks more like NUJV. I always figured maybe British semaphore is different from American semaphore. But according to a book I bought yesterday, "Beatlesongs", the semaphore is actually reversed; if you hold the album up to a mirror, they're spelling out LPUS ('elp us!) Sure enough, they are, although George's S looks a bit sloppy, more like an N. LPUN!
