A cab driver in Pittsburgh named Sam Snow got the surprise of a lifetime recently when he picked up a passenger who turned out to be his #1 rated quarterback of all time, Denver Broncos legend John Elway.

Not noticing Elway was seated in the back seat of his cab, Sam the Steelers fan was asked to rank his top-3 all-time quarterbacks. Although he was unaware of Elway's presence he immediately listed John Elway as #1 ahead of Tom Brady and his hometown guy, Ben Roethlisberger.

Sam was eventually told to turn around and he recognized Elway right away. Check out the awesome footage below.
