What we have here is an everyday, football fan shooting the shit, when suddenly he is coerced into ranking John Elway as the best qb of all-time. D.C. cabbie, Sam Snow was oblivious to the fact that he had John Elway in his cab when he started spewing his football rankings. Elway, Brady, and Roethlisberger were his top 3 quarterbacks(whole other issue), when finally he realized who was in the back seat.
It is always entertaining when someone is genuinely caught off guard with excitement. I’m willing to bet the passengers brought John Elway to the table before the video started, and Sam just went with it like a pro. Fortunately for Snow, he said the right things, and most likely pulled off with a fat tip.
