Haha, that's good.
Last year at a Devil Rays game me and some friends were heckling Ted Lilly. Everyone knows dude is so unemotional on the mound. It was on like a random Tuesday night, so obiously at a D-Rays game there were like 10 people in the stands and in the dome you can hear everything.
After a bad inning he was coming off the mound and my friend goes "HEY LILLY, GO PICK A FUCKING DAISY", he looked up and put up this huge smile. Favorite moment at a game, only time I've witnessed acknowledgement to heckling.
