Definition of a Home Run

[AgonyandIvy]

I'll leave to no less an authority on catching flies outside the field of play than Bugs Bunny himself. In the classic BB documentary short feature "Baseball Bugs", in the last inning, one of the Gasehouse Gorillas hit a screaming line drive from the Polo Grounds that flew out of the entire ballpark, all the down to the lower east side where Bugs went into the Umpire State Building, up the elevator out the observation deck and up a flagpole. And even then he had to throw his glove in the air, but he caught the ball on the fly and the umpire on the scene immediately called the batter OUT! . .

Also, you see all the time fielders reaching into the stands to catch foul balls for outs. It doesn't matter where it's hit, if a player runs out the gate, up the stairs down a tunnel and catches a hit ball on the fly, you're OUT!
