Flying Rats!
Ah, someone has taught rat brain cells to fly a simulated F-22 fighter jet. Rats with weapons…I can’t foresee anything that could go wrong with that, can you?
(They were originally going to use cat brain cells, but the planes would lose interest and stare off into the distance.) 
Update: William Gibson recalls author Cordwainer Smith using laminated rat brains in his 1950s SF stories performing the functions for which we would later use computers.
