I sometimes cover myself in butter and lock myself in the oven
Why would you do this?
I want to be turned into bread.
Nice joke, man. Careful you don't get stuck in the oven, though.
I'm not joking. The fire will be very enjoyable.
While it's unlikely you'll be able to squeeze yourself into an oven, it's concerning that you're seriously considering such dangerous behavior. It sounds like a cry for help. I strongly urge you to seek a licensed mental health practitioner.
