5. Identical twin Gerald Levy and Mark Newman were separated at birth and raised in different cities. When they were reunited at age 31, they discovered some astounding similarities. Both were volunteer firefighters, wore mustaches, and were unmarried. Both like to hunt, watch john Wayne movies, and eat Chinese food. They drank the same beer, held the can with the little finger curled around it, and crushed the can when it was empty.
