You know, I always wanted to be a singer. I just work for old slime-head to pay the bills.
Before I worked for old slimeball, I had a pretty nice gig with the folks back home. New sights, big guns, plenty of fresh air... granted, most of the time the air was poisonous. Still, I loved the work. It's too bad there's a price on my head now.
