There sure is an advantage to writing lyrics when there is no fixed tune! Although I used my former notes I overturned the meter of the verses:
do you see that fat old fart
tryin' to sqeeze her belly | through the diner's door
I could not believe my eyes
when I watched her at the counter | ordering some more
did you see that haggard man
who dragged his old and weary body | 'cross the busy street
such sights should be banned
when you're in such a sorry state | it's time to retreat
The pipe symbols indicate an envisioned break in the meter or tune, the second parts are the more important ones. Here, the meter is exactly the same for:
through the diner's door
ordering some more
cross the busy street
it's time to retreat
I scrapped the stupid image of letting out the air of fat people (an image that actually does pop up in my mind from time to time, as stupid as it is). One of the reasons is that I could not find a feasible rhyme for "balloon"(!). I also scrapped the reference to cripples, giving ordinarily ugly people preference ;-) The song will be mean enough, anyway ;-)
