Movies that went from R to PG?

So I was thinking of the movie Major League the other day because of Opening Day, and I show movies in my classroom during lunch but was like, damn, it's R I can't play it. Then I realized Major League 2 is PG and essentially the same movie.

How many sequels can you think of that make a jump from R to PG? I know a few that drop to PG-13, not down to PG, and it was in 94, so PG-13 existed then.
