Daniel Benjamin Burroughs (Jim Byrnes), a.k.a. “Lifeguard”, a physically challenged employee of the FBI’s Organized Crime Bureau, who was the phone contact for special agents working undercover with the Mob.
Sitting in his wheelchair, Lifeguard (a.k.a. “Uncle Mike”) assisted agents in the field by offering them emotional support and by transmitting vital information to and from superiors.
In real life, actor Jim Brynes lost his legs in a car crash in 1972. He was pushing a stalled truck on a highway in Canada when he was hit from behind by a car.
Nine months after the accident he was fitted with prostheses and relearned to walk. He once said, “I’m physically handicapped but I’ve gotten this job because I’m good at it (acting), not because I’m handicapped.”
