Was this one with a fire station cook, by any chance?
If you have a "three-alarm" fire, it means that fire crews from three different stations had to respond. It was a big fire.
Sometimes we use this for food. Three-alarm chili, for example, is really spicy chili.
A 20-alarm fire would be a huge fire. A metaphorical 20-alarm chili would be so hot I know I could never eat it. A 20-alarm throwdown means it's a big, big competition. It would be funny if the setting were a fire station.
