When the new employment exchange manager Bradshaw insists that everyone can be helped, veteran Hooper gladly passes on the hopeless case of Frank Spencer. Both his serial disaster-record and 'qualification' (25 meter breaststroke, after 'attending' many schools, till age 11, no actual classes) support Hooper's point amply. Yet Frank acts indignant, and Bradshaw insists on trying - betting he'll keep a job for a week. The only way to win is to employ Frank himself, but this proves far more costly and dangerous for everyone and everything.
