I haven't heckled in years, but when I was a young man I was quite proficient at this, but I kept it at the professional level. When I was a teenager, my dad took my best friend and I to a Royals game...guys trip! Anyway, we had amazing seats for heckling and were in the second or third row in right field, immediately beside the bullpen.
Royals were playing the A's, and Canseco was in the RF. We were laying into him about all sorts of stuff, but leaning pretty heavy on him dating Madonna. Later in the game, a Madonna game came on the PA and he turns to us and points and starts gyrating and dancing. Well played, Jose Conseco, well played.
