Gene Simmons of Kiss is attempting to trademark the devil horns hand gesture.
No, we're not making this up, promise. He's filed an application with the US Patent And Trademark Office, claiming it was first used 'in commerce' Nov. 14, 1974.
That date lines up with the band's Hotter Than Hell tour.
Here's the diagram he's used to demonstrate what the horns are.
Thumb out or thumb in, that's the real question.
Here's a reminder of what Kiss are about:
Gene might run into trouble with his application, though.
As The Hollywood Reporter pointed out, the gesture has been used for thousands of years in Buddhism, and is also the American Sign Language sign for 'I love you'. It's also an offensive gesture in many countries.
Oh, and The Beatles used it too, back in the sixties.
