This literally just happened to me.
About an hour ago I was putting my toddler down for a morning nap when my fire alarm went off. It stopped as soon as I ran out into the hallway.
I searched all around. No smoke and no fire. I shrugged and went back to check on my kid.
A little while later I was feeling peckish, so I went to the kitchen to start lunch.
My kids love bread sticks, so I decided to make some for them to go with the left over lasagna. Like a moron, I placed them directly on the oven rack. It works for pizza, no?
As the food was warming, I stood at the counter checking my email. Well a few minutes later I heard some kind of mini explosions right beside me. I looked down, and the fricking oven was on fire! Butter was dripping off the bread sticks and feeding the flames.
I yelled something along the lines of, "Holy Sh*t!", grabbed a large bowl, and filled it with water. Then I flung open the oven door and threw the water on, because I was in full panic mode and forgot that grease fires and water do not mix.
Fortunately, the water cooled the bottom of the over down enough to stop the flame, and most of the available fuel was used up by that point.
The odd thing is that despite the house filling with smoke, the alarm did not go off.
I can't help but think that the timeline got a wee bit mixed up this morning.
