Of course I've heard of Broadway Joe but he's not crossed my mind for many years.
Same here. Didn't even know he was still alive. I've never seen the commercial the OP mentioned...must be a regional thing. Lots of annoying ads, but that's not one of them.
I think 'Broadway Joe' looks like a jerk with those chalky white teeth. Wonder where he bought them? Heck - I think he's a phony with or without the chalky teeth!
