Heads in Jars was invented in the year 2999, created by Ron Popeil's head. They can be used to store and preserve the heads of celebrities and even long dead historical figures from presidents to historical villains, through special cloning from the DNA of that person. They can even use robotic limbs in the jar or attach themselves to move around. The liquid inside is called H2OGfat.

It's also possible to revive already dead heads. Some examples of such characters include Elvis Presley and Richard M. Nixon.
