A cab driver, who is a big Pittsburgh Steeler's fan, freaked out after he realized John Elway was in his car.

Elway's family kept asking the driver who the best quarterback was of all-time and he said Broncos legend John Elway. Keep in mind, he had no idea that the NFL icon, now General Manager, was in his cab.

Once they tell him to look back, he freaks out after noticing Elway in his car. All that he can say is, "I have to take a picture." And I'm sure he did once they got to their destination.

This is so cool. Have you ever shares a vehicle, elevator, or seat with someone famous? Let us know in the comment section below.
