WASHINGTON, Iowa -- A burger at an Iowa restaurant is so hot people have to sign a waiver to try it.

Anyone that tries the "Hellfire Burger" has to wear gloves and goggles just to take a bite.

Xtreme Smokehouse and Grill puts cayenne pepper, pure chili extract and a hot pepper relish on the burger before topping it off with grain alcohol and lighting it with a spark.

Now that is one hot burger.
