An electric shock occurs when a person comes into contact with an electrical energy source. Electrical energy flows through a portion of the body causing a shock. If you scuff your feet on your living room rug, you pick up extra electrons and have a negative charge. Electrons move more easily through certain materials like metal, which scientists call conductors. The shock he received was a result of the quick movement of these electrons.
