In "Joey's Place" the family redecorates the garage into a bedroom for Joey. But two episodes later, in Our Very First Promo (1987)Jesse searches for a "monster" in the unfinished garage.. In the next episode after the "monster" the garage is back to Joey's room. this does happen a lot with TV shows, they are filmed in one order but then they are aired in a different order. SO this would not really be a goof but just that the network aired the episodes in a wrong order.
