Activator Ring
Sega wanted in on that peripheral money that Nintendo was raking in, so they created a little item I like to call the "Ring of Death." Nothing spells out safety better than a plastic ring sitting six inches above the ground. It was a foot magnet and usually meant a face-first fall into whatever was on your bedroom floor. The Activator Ring didn't work terribly well with fighting titles, as it was originally intended, but it did give us the first instance of people looking like idiots while trying to play a game.
