A friend was visiting me and we got pizza. I was in the other room, so I completely missed what she did next. She put the pizza box in the oven, turned the oven on, and walked out. I guess she was trying to keep it warm? Next thing I know I smell something burning. I run to the oven and the pizza box was on fire!!
I grabbed it, threw it on the balcony and doused it with a glass of water I had sitting there. She said her mom always stored pizza in the oven so she just did that. I was brought up you never leave anything in the oven, and to always check before turning it on. Plus, I don't quite get not refrigerating it!
Of course, my friend did call me once to ask me how to brown the hamburger she was making for Hamburger Helper, so perhaps she might fall under the culinarily challened anyway.
