Great American Ballpark in Cincinnati turned into a nightmare scene straight out of "My Girl" on Monday ... when a swarm of bees invaded the stadium -- forcing officials to delay the start of the game.
The Reds were gearing up to take on the San Francisco Giants when the bees came ... you can see in photos and video there are THOUSANDS (maybe millions?) of the flying insects on the field.
In one shot captured by NBC Sports Bay Area, you can see just how close the bees came to the Giants dugout.
