An old guy is driving home. It's very late at night. He's cruising along the highway and he's some considerable distance from home. Suddenly, he feels himself having a heart attack. He says, "Oh my God. It's the big one!"
Thinking quickly, he takes the first available exit. As luck would have it, he winds up in a residential neighborhood, full of houses. He pulls over to the side of the road behind some parked cars.
He's fading fast, but he has the presence of mind to pull out his cell phone and call 911. He says to the dispatcher, "I need help. I was driving on the highway and now I'm having a heart attack. I think I am going to die!"
The conversation with the dispatcher goes like this:
Dispatch: "Where are you now?"Man: "I don't know where I am."
Dispatch: Can you look at the map on your phone to tell me where you are?Man: I have a really old cell phone, it doesn't have GPS or do any mapping.
Dispatch: "Well, what exit did you take from the highway?" Man: "I don't remember."
Dispatch: "Were you going north or south, west or east?"Man: "I don't remember."
Dispatch: "Can you tell me what street you're on?" Man: "I'm in the middle of the block of houses in a residential area. I'm parked in front of a house, but it is dark and I don't see any street signs or a house number."
Dispatch: "Start blowing the horn, maybe someone will come out of the house." The man blows his horn, but no one comes out of any of the houses.
The dispatcher then asks him one more question. Minutes later, an ambulance shows up at the man's location to save his life.
