A few people here have already said "Transformers", but Transformers – The Movie (1986) was basically just an ad for the toys. There is also a rumor that they put in a single "shit" in the dialog so it would earn a PG rating, so that kids would have to go with a parent, and the parent would have to sit through the commercial, so as to understand what particular toy the kids were screaming for this time.
