Taking the freakiest drug trip ever. LSD, shrooms, marijuana, ecstasy, morphine, all of it!
And then committing suicide by:
Finding a high platform, about 20 meters high.
Tie a thin metal wire on something, on top of the platform.
Tie the other end of said metal wire around my throat.
Dip my hands in super-duper-mega-glue.
Glue the hands to the sides of my head
Jump.
Result = At first, it'll look like the body ripped its own head off
