I was at a live event a couple years back and I remember Aaron shouting "This song is about a piece of shit." before singing The King of All Excuses which got me wondering, who exactly is this song directed to?

From what I read or heard... it was the guy who WAS building Aaron's house.

Yeah, I was at a concert at the York Fair in '06 and I remember him shouting the same thing before this song started. I always wondered who it was about.
