Who's Johnny Mustard?
"Put some mustard on it!"
My folks bought a house in 1964 from the Cruikshanks, an old couple who left their dog Mustard behind since they were moving to a retirement home and couldn't take him. Because my middle name is John, my porn name is Johnny Mustard, according to the old-school rules (middle name + first pet).
I always thought it had a nice ring to it, and decided to use it as a pseudonym if I ever needed one. Which is kind of ironic because I headlined under my real name when I was actually making skin flicks back in the late '80s. Y'up!
