This was a segment on the "King Kong Show". Tom is a private eye for an organization called .T.H.U.M.B. (The Tiny Human Underground Military Bureau). His partner is Swinging Jack, and together they fight the evil members of M.A.D. (Maladjusted, Antisocial, and Darn Mean). They became tiny from a shrink ray that accidentally went off while they were standing in front of it.
