Tourists run up stairs like Rocky and bump into...Rocky

WHILE sightseeing in Philadelphia, three tourists decided to run up the Philadelphia Museum of Art steps just like Sylvester Stallone did in Rocky.

And when they got to the top someone said: "You guys got up here pretty fast, you're making me look bad."

It was Sylvester Stallone. 

The movie star then posed for a selfie with the three men, which was later posted on Facebook and has been shared more than 2000 times.
