A guy I know played in a band, and they were opening for this other band, and for some reason the promoter didn't bother to put their name on the bill. So the poster had just the name of the headlining band plus "& Support Act".
So they changed their name to Support Act.
A couple of months later the same guy stole a few hundred bright yellow stickers with the word "Sortirgut" on them at work, so then they changed their name to Sortirgut so they had free stickers to sell.
