version 1
The biker was on the road. The biker’s engine died so he walked back the other way. Earlier he saw a parked car in front of a restaurant. He was looking for an engine in the car with his arm. What he didn’t know was that the car was running. The driver got in while the biker’s arm was still in the hood. It dragged the biker for miles, he was twisting and turning. His twisting and turning loosened his arm and snapped his leg. The car stopped because the biker’s bike was in the middle of the road. The inertia snapped the biker’s arm off. The biker was still alive but due to the large amount of blood lost, he passed out and eventually died. The aliens just happened to stop by.
version 2
The aliens placed a phony accident using their advanced technology. They were tired of just “beaming people up”, so they waited ’till someone came. They’re still waiting….
