Frank usually serves as a foil to his evil boss, Dr. Forrester, and is frequently on the receiving end of many of Forrester's experiments or punishments. He is subjected to many painful deaths but always returns alive and well shortly afterwards; whether this rapid recovery is a quality bestowed upon him by Dr. Forrester or a talent that Frank always possessed (making him uniquely qualified as a mad scientist's guinea pig) was never explained, since it was, after all, "just a show." In the episode "Laserblast", Pearl finds his spare head in a box, Dr. Forrester having made Frank's head explode years earlier in "Gunslinger". Occasionally, however, Frank gets revenge on his taskmaster by directly or indirectly causing Forrester harm. One significant example of sidekick payback occurs in episode #619 "Red Zone Cuba", when Frank, supposedly owing the mob "50 large", passes Forrester off as himself, earning the evil scientist two severe beatings and an episode-long stint in full-body bandages.
