It was given to me on a hat by the father of one of my students; the father was a steely, competent type guy with the famed "linebacker stare." He and the wife gave it to me at the graduation and all he said was "...so you're the guy who helped Steve? God bless you."

I never wore the hat as I was afraid I'd get bushwacked (no pun intended ) by some unhappy guy(s).
