A man was driving to work when a truck ran a stop sign, hit his car broadside, and knocked him out cold. A Passersby pulled him from the wreckage and revived him.

He began a terrific struggle and had to be tranquilized by the medics. Later, when he had calmed down, they asked him why he had struggled so.

He said, a bit sheepishly, “I remember the impact, then nothing. I woke up on a concrete slab in front of this huge, flashing sign. Turns out I was in a petrol station and somebody was standing in front of the ‘S’ on the ‘Shell’ sign.”
