How to Cook Bread on a Stick Over a Campfire

I love hanging out in my backyard with my dogs. My coworker shared this video with me he made about cooking dough on a stick over a backyard fire. I've heard of people doing that, but never tried it. After watching the video, I feel like I could. He just used frozen dough from one of those pop-open tubes and it looks like his stick is a broomstick or something.
