I have been working in a department store over Christmas and as I served a woman at the tills, I noticed that she had JPJ's symbol on her wrist. So, eager to acknowledge a fellow fan, I said "you're a Zep fan then?" she looked at me really puzzled and said "sorry??" "The symbol on your wrist..." I pointed out. She replied "Oh no, I am a big fan of the tv show Charmed. It's from there." Then I was all bamboozled as I didn't know what she was on about! I googled it.. and here's a picture, symbol included
Edit to add: typical.. the first time I don't fully check a thread in case someone else has posted what I am about to post! Sorry, just seen that reids has already mentioned about Charmed
