Russell James Liberman was an American funny car drag racer, nicknamed "Jungle Jim." In 2001, he was named #17 on the list of the Top 50 NHRA drivers of all time. Liberman was known for driving backwards at 100 miles per hour (160 km/h) after doing his burnout.

Funny Car is a type of drag racing vehicle and a specific racing class in organized drag racing. Funny cars are characterized by having tilt-up fiberglass or carbon fiber automotive bodies over a custom-fabricated chassis, giving them an appearance vaguely approximating manufacturers' showroom models. They also have the engine placed in front of the driver, as opposed to dragsters, which place it behind the driver.
