Whenever I go to the fair, I have to get a corndog.
Oh!  It's a sausage on a stick right?  It's covered with a thick cornmeal batter, and then deep fried as far as I know.
Yes!  Oh do you happen to know when they were invented?
I do!  In 1929 a US patent was granted for a cooking apparatus, and it described corn dogs, and other stick-impaled food.
Wow, that's cool fact. I heard the Korean ones are popular now. Do you know where I can find some?
