Finger 11's old name

I didn't know this until just a minute ago when I read it on the internet, but the band Finger 11's old name used to the Rainbow Butt Monkeys. That's one epic band name. They totally shouldn't have changed their name...

Finger 11? What kinda name is that? I wouldn't be surprised if they were all just playing charades one night and those were the three last words and one of the band members just noticed it...
