GREENSBURG, Pa. (KDKA) -- Last Friday night, comedian and former host of The Tonight Show, Jay Leno was in Greensburg for a stand-up comedy show at the Palace Theatre. While the show went off without a hitch, what happened before the show has everybody talking.

The user's theory goes on to explain that Leno decided to take the chance with a shortcut down the hill. “Since the path was rough, not maintained and erode away, he tripped and rolled down the hill, hitting his head on the exposed rocks and earth on the way down the hill," reads the theory.
