I know I can Google and get mostly whatever info I'm searching. However, that's not exactly my point here.
I had a random thought today, shocking, I know. Who decided to put a hot dog on a stick, roll it in batter and fry it? And why call it a Corn Dog? Yeah, yeah, it's corn breading. I get that. But, seriously, why?
Whoever took that and ran with the mustard idea was the genius.
