I Love Jokes And Riddles

While driving in a lonely road, I stopped to pick a hitchhiker.

Few miles later he asked me: "Aren´t you afraid that I may be a Serial Killer?"

I put my best smile and without looking at him, I answered in a whisper: "The probabilities of finding TWO Serial Killers in the same car are quite low"

He remained silent for the rest of the drive.
