I also discovered, on the Muppet Wiki guide for Episode 594, there was a segment "Some clowns, more clowns..." that was edited out of the HBO Max broadcast. Was this due to licensing issues with the Ringling Brothers/Barnum and Bailey Circus, even though the company has been defunct for five years?
I do know that, in the HBO Max release of Episode 1836 (Season 15 premiere), the segment "Counting the circus clowns" was likely kept intact, implying it may not have been licensing issues with the circus company that applied with "Some clowns, more clowns..." So what on earth could be the reason?
