I'd be having rough but sensual sex with Velma in the back of the Mystery Machine. Scooby Doo would pop in, think I'm hurting his crime solving buddy and instinctively bite my throat, killing me by blood loss.
I'd be just a random rider of rohan during the battle of Minas Tirith who foolishly provoked the nazgul leader by calling him "The Bitch King"
After he disentegrates my sword with his shout he stabs me with his fell blade and I black out. I wake up after the battle and am being tended to by my hot girlfriend Eowyn. She tends to my every need for nearly a week before I finally succumb to my injury and die, blissfully.
