Oh, I actually tried that once during a time in my life that I was trying to avoid relationships, and I had a very BAD experience with a woman becoming furiously angry with me when she found out that I wasn't actually married.  It was ugly.  I still haven't figured out why she reacted so angrily, but she definitely went out of her way to try and punish me for it.  Besides, like I said, the other employees know me and there would be questions if I suddenly started wearing a wedding band.  I'd rather not have to start weaving a web of lies.
