Definitely the wife's fault. A worker of stationary machinery (the oven) should at no time leave the general area while it is operating unless it is locked out and tagged out. You should have her go through the OSHA documentation pertaining to heat generating machinery as a refresher. You'll be eating pizza for a while.
Actually this kind of reminds me of this one time when I still lived with my parents, my mom got me to turn on the oven at a certain time when I get home to start boiling potatoes. Knowing absolutely nothing about cooking, I just assumed the time the told me was timed so that when she gets home, it can continue going for a little while and then be stopped. I would go check it once in a while to make sure nothing is catching on fire or anything but otherwise did not really touch it.
Then my dad got home, and he tended to be in the way a lot when he was in the kitchen, his supper was always this huge production and you better GTFO of his way. So I kinda assumed that since he was there he was taking over tending the pot. I did not want to go check it and be in his way. He was always really grouchy until he would finally sit down and eat.
At some point I started to smell something. all the water evaporated and they were burning in the pot. My dad moved the pot on the counter and it made a huge burn mark on it. My mom got home around the same time and now they were both on my back about it. HUGE ordeal. That burn mark stayed there as a reminder of my screw up. lol. Stupidity on my part for assuming a lot of things in the process, but at the time, I just did not know any better.
Men and cooking don't mix.
