Found this in a piece on MLB.com about minor-league baseball announcers. I've often wanted to do this to Littlefield myself:

Landon Sears, the young Hickory Crawdads' announcer, saw his professional livelihood flash before his eyes during a recent game.

"At our home games, we do this between-inning promotion where our game-day employees throw Hamburger Helper into the crowd," explained Sears. "A lot of the time, they'll throw some up to me in the booth, and then I'll toss it back down to the crowd."

"Well, at a recent game we had [Pittsburgh Pirates general manager] Dave Littlefield in attendance, and he was nice enough to come on my broadcast for an interview. So, sure enough, as soon as we come back from break this packet of Hamburger Helper flies into the booth and smacks Littlefield right on the cheek. I just froze. I didn't know what to do. Fortunately, he took it stride. Just picked it up and placed it back up against his cheek. He even posed for a picture like that."
