I've known a few guys name Shannon, a guy named Jamie, girls named Shawn (and guys whose name was Shawn who spelled it the same way-- I was told that Shawn is the girl spelling, but I know at least two guys who spell it Shawn), and I had a gym teacher who went by Shelly (his name was Sheldon).
Edit: Oh, and I had two band directors in high school-- they were married, and both named Robin, but the guy went by Rob. How weird!
