Does anyone else remember Tom of T.H.U.M.B.? His sidekick was Swingin' Jack? We had a cat named Swingin' Jack back then!

Ha ha ha! I just found this:

Tom was an average member of the U.S. Intelligence Maintenance Department. He was sweeping the floor when he fell down the stairs and whilst being helped by his faithful assistant Swingin' Jack, an oriental Martial Arts expert, accidentally turned on the shrinking laser beam ray gun and both were miniaturized. They gave their height to their Country, creating the Tiny Human Underground Military Bureau (T.H.U.M.B.)

Tom's office and home was a filing cabinet. The Chief used him when regular sized men were too big for a job.

The main enemy was MAD - Maladjusted Antisocial and Darn Mean, an organization of Scientists trying to destroy the world for their own means.
