When I was a kid around 6 I kept bugging the guy that did our yard for some chewing tobacco and he finally gave in and cut me a piece of Bull of the Woods and 15 minutes later I was puking my guts out. That was the last time tobacco ever entered my mouth. I smoked cigs, pipe and now am a cigar smoker but unless I am puffing, it stays in my hand or ashtray, not my mouth.
But I gotta say, it doesn't matter with baseball players, they're gonna spit if they're chewing Chiclets. If I was a bird, I hang around the dugouts for the unopened sunflower seeds.
