Barry and Paul are brush salesmen for No Slacking and come to the house of Dr. Bonkers, Mad Scientist. It is a mess and Paul thinks they should tidy it up but then they discover the 'creature' lying on the slab. Dr. Bonkers needs a brain to bring it to life, or, as second best, whatever passes for a brain in Paul's head. Barry rings their boss to come and help, and the upshot is a monster who abhors slacking.
