I'd clean myself off from all the blood and gibs, then probably try and find somebody nearby and tell them what happened. It was a young man I found, about 20 or so. He didn't beleive in the whole spontaneous combustion phenomenon, but I showed him your puddle and he soon realised that it actually had happened.
A little boy (it was actually a 4ft 81 year old) rode by on a unicyle and fell off, knocking his old-ass head on a tree and landing on your remains. He was knocked out, so he (quite predictably) didn't get up or move a muscle. To anybody driving by the scene could have looked like somebody had spontaneously combusted and an old man had fainted over them. But luckily nobody was around.
Or, rather, there were quite a few people around, kids, mums with pushchairs, traffic wardens, a police officer, and ice cream cone man, a milkman, a bodyguard for the mayor, the mayor himself, some kid with a tatoo that read "L0PL", the Mayor's wife, a ninja kangaroo, a fireman, attracted from a nearby fire, the mayor's mistress, a secretary, a head chef from a nearby reasturant and a man in a banana suit all gathered round and looked at what was first suggested and then began to be beleived as a peice of modern art. They thought this pile of M.O.T's bone peices, muscles, blood, pancreas, lungs (well, one) and a few teeth and an old man that looked like an 8 year old was a peice of modern art!? What the hell! I was going to tell them, I thought. I got up, and edged closer to the middle of the circle of people. I refrained from going straight in the center, as this was where the mess was, but I made my way deep enough to stand out. I raised my hand, though I were back in school, and the crowd eventually drew silent. I opened my mouth to speak-
-SUDDENLY the old man leapt up ~ and blew the hell up!
Everybody made a desperate attempt to get away from the wave of blood, old man spit, hair and testicles as the stuff moved ever nearer. There seemed to be no escape - this guy had some serious force to his explosion, unlike Master_Of_Time's subtle pop-squish. Everybody was going to die. There were about 10 seconds left.
SO..
What would you do if you were in this situation?
