Kinda makes sense since peanut butter is made with ‘roasted’ peanuts.

#13 in really old photos you can see the dead person being much more sharp/in focus than the other (living) people in the photo. This is because early photos needed a long exposure time, and while the corpse sat perfectly still it is impossible for living people to be completely motionless for the time it took to take a photo, causing them to be slightly blurry/"out of focus".
