of baseball game wedding proposal prank

The Yankee Prankee: This is a prank by some guy on his friend, Streeter. The guy posted a wedding proposal on the big screen during a baseball game on behalf of Streeter, asking Streeter's girlfriend (Sharon) for her hand in marriage. The only thing is that Streeter and Sharon do not know of the proposal. -

There was confusion between the couple when the message was flashed on the big screen. In the end, Sharon walked out of the stadium but not before slapping Streeter in the face.

Call it funny or call it mean? You be the judge.
