My amazing one-two punch with the microwave in 7th grade:
- We had a few slices of pizza in the fridge wrapped in tin foil, and I wanted to heat them up. As my mom was leaving the house, I asked her how long it would take if I used the microwave instead of the oven (lazyyyy) and she told me, and also said "make sure you take it off the tin foil" but I thought she told me to keep it ON the tin foil

Left a nice little scorch mark inside the microwave...
- The next day I was making Easy Mac, and I absent-mindedly added the water AND cheese mix before I heated it up. ****ing. cheese. ****ing. EVERYWHERE
I wasn't allowed to use any kitchen appliance for a few months after that
