Baby-sitters club, Family Ties, Sliders (this scifi show from the 90s) had a male Mallory in the later seasons - it came from a last name (the character was originally a guy named Quinn Mallory)
I definitely hear Michael J Fox saying it. Followed by Meredith Baxter and Michael Gross with that exasperated tone.
It's ok, but I kind of hate the nn Mal on a girl.
