Ideally, I'd like to give this immortality thing a shot. Otherwise I'd want to team-up with Danny Lee and go out in a hail of gunfire battling the Triad, like Chow Yun Fat did in The Killer. With my dying breath, I'd pass Danny my lighter (even though I don't smoke. It's a guy thing.) so he'd always remember.
Then I want an Irish Wake - I want my bullet-ridden corpse planted on a stool at the local pub by my buddies, with some Irish tunes blasting as everyone parties.
At the funeral, I have a set list all ready to go music-wise ("Afterimage" by Rush, Buckley's "Last Goodbye", etc.), and I have a spot all picked out - a nice, green, park-like cemetery. Which happens to be near a waste dump. Some kid horsing around knocks over a drum of mysterious chemicals, gasses are released, mixes with the atmosphere, it rains on my grave, seeps into my moldering corpse... and I'm BACK, FOLKS!!! BRAINS!!!!
