In this enjoyable episode, the garage is taken over by an eccentric new owner, and leaves the Fonz having to find another job.
He eventually gets a job seeling encyclopedias door-to-door, but is clearly not cut out for the job, and does not even make a single sale. He does manage to pick up an attractive woman, though!
This is another episode that centres around Fonzie and Richie, something that was typical of the third season.
The final scene, without any dialogue, is really funny, and illustrates the broad range of humour the show was capable of.
