Here's how it all started. When I was seven, I came home from Sunday school (yes, really) and turned on the TV. There was usually a movie playing on the local non-network affliate channel around Noon on Sundays, and on one day I cranked the TV just in time to catch Help!.
If you've seen the movie, you know it starts with an attempted human sacrifice that fails because the victim isn't wearing the sacrificial ring. Where's the ring? Cut to a shot of Ringo Starr's hand while he's playing the drums as The Beatles play "Help!"
