I would have a Mustang, a Camaro and a Charger come out on the field. On fire. Doing donuts.
While this is happening, combined military marching bands would come on the field, playing stars and stripes forever. Their instruments would be on fire and their drums replaced by artillery pieces.
The military precision jumping team would then parachute into the stadium (even more awesome if it wasn't an open stadium) On fire, of course.
Finish it off with the star spangled banner and cannon. Lots of cannon, firing firework mortar.
While the bodies are removed, the fires put out, the field repaired, they can do game analysis and show all the commercials they'd like.
