The subtitle of the book is HECKLING IS A BAD THING?
Rob Szasz's book on heckling is, surprisingly, one of only two books I know of on the subject. The "Tampa Bay heckler" has written a book about his experiences in good-natured heckling of opponents of his team, the Devil Rays (who need all the help they can get).
Ron is always tasteful in his heckling (and in the book), avoiding off color language and steering clear of anything personal that would be hurtful to the players he targets. Anyone who has watched a Tropicana game on TV (or been there) has heard Rob Szasz. He makes the point that he most enjoys the players who get a chuckle out of his heckling. The ones who can't take a joke aren't really very good targets, anyhow.
The whole thing is in fun, and so is the book. I wish we had more fans like Rob Szasz.
