OK after seeing all of the opera singer hot dog vendor stuff, here is the full story. He is one of the biggest sales vendors of the Detroit Tigers at Comerica. He has the dugout to dugout area behind homeplate. What he does is he sings "hot dog" in an opera voice as he is selling. When I went up their for a game a couple of years ago he got in my face (all a part of his act) and started to ask me what my deal was. Then he went on to expain to me how since I was at a baseball game I had to eat hot dogs. I told him that I was from Chicago so we ate Brats and Polish (total BS but I was playing along too) So the next hot dog vendor that came by I bought a pair from him and got his attention and rubbed it in his face.
Anyway yeah his routine is cute, but trust me after 3 hours of hearing him sing Hot Dog over and over, I wanted to kill him.
Anyways he was at Comiskey for openning day, because they bring in vendors from area teams when our attendance is way more than usual. It will happen again during the Cubs series.
