Where can I get some corn dogs a.k.a. dagwood dogs?

Answer 1

Go to the fair or the freezer case of your local grocery store.
I recommend you make them yourself since it's just cornbread around a hotdog on a stick.

I see them all the time in the frozen food aisle at the supermarket. I love the ones at Hot Dog on a Stick at the mall.
