Look It's a Bird It's a Plane, It's a Resignation Letter?

Ha! The other day (Monday morning last week to be exact) while I was sitting at a red light on my way to work. I saw this skywriter message. It was so funny I grabbed my cell phone quick and snapped a picture. Clear as day it reads... BOB, I QUIT... How's that for a resignation letter on a Monday morning? Don't we all feel like that on MONDAYs? Edited to add: Yes, this is a real photo I took.
