oh! there's "why don't you write me" by paul simon, otherwise known as the pathetic desperation anthem:

starts with:

why don't you write me, i'm out in the jungle
i'm hungry to hear you...

and i LOVE the bridge:

sunday monday sittin' in the sun
hopin' and wishin' that mail would come
tuesday
hadn't got a word (mmmm mmmm mmmm mmmm)
wednesday thursday ain't no sign
drank a half a bottle of iodine
friday
woe is me i'm gonna hang my body from the highest
treeee-eeeee-EEEEEEEEEEEEEEEEEEE
[shrilly] WHY DON'T YOU WRITE MEEEEEEEEEEEEEE-EE-EE?
