This quote appears (with some added profanity) in the movie Bull Durham. Umpiring is serious business and most folks I know take it very seriously. Of course, that does not mean there are not moments where some fun is appropriate.
Check out this play:

The umpire down the line has a ball magnet in his pocket. Instead of possibly taking one in the face he decides to hit the deck. Being dedicated to his job he spins while on his backside to confirm the ball landed foul – he even makes the call.
The fans were giving him the Bronx cheer (not a euphemism as the game was in New York). He gets up and proudly tips his cap. Sometimes that is all you can do.
