Deep fried turkeys exploding (true its happened)(look up fried turkey disasters there is a wide variety of those)
Frosting falling off of cakes (happened to me)
One time I forgot to put baking powder into banana bread and it was so rubbery like that it literally bounced lolol.
Hope I gave you some ideas.
During Thanksgiving or Christmas once, everything was going fine, my mother-in-law had all the snacks, sides, desserts, gravy, everything done. When it came time to pull the turkey out of the oven, it was cold, she'd never turned the oven on. So my sister-in-law and I went to pick up pizzas and that was the meal. Pizza...with mashed potatoes, gravy, green bean casserole, the works. Odd.
Butchering fresh chicken for the guest and one of the alive chickens runs in pro the dining room!!
I'm writing a stoy and I can't think of a single one.
