* FULL DISCLOSURE * The "Truck Driver" was also a harvey mudd grad school dropout, who had a serious aptitude for math. He wasn't Bubba with a pocket donut... He was trying to make ends meet at the time and I gave him a chance.
On of the best Lisp programmer I ever picked up was a musician, who wasn't getting enough gigs. Had an advanced degree in Math from Carnegie Mellon, so I said "see if you can wrap your head around this and let's talk". Rest is history.
