Cover art for As Can Be lyrics by John Frusciante

I agree with kizzykaz...for the most part...

to me i just use it as " I'm _____ as can be "

whatever you're feeling just feel that way to the highest extent you can so that it's true....happy, sad, mad, depressed, etc...

one of my favortite of his songs...
