In syndication and daytime network repeats, the tag scenes are usually cut.
When airing on Pluto TV, every episode has been edited to cut out parts of them, presumably, to make room for more advertising.
In March 2001 viewers watching reruns of the series on Nick at Nite reported that in episode 8.11 "The Charming Stranger", John Ritter's genitals could be briefly seen slipping out of his blue boxers when his character throws himself on bed. Nickelodeon confirmed this goof and announced that the scene would be edited out of all future airings of that episode.
