"... for Flintstones fans, something might have felt a little off about the caveman's feet being so sensitive to tickling..."
It's curious that someone's made a connection and made it the subject of an article, but even more curious that they'd think that fans would generally be wondering how Fred Flinstone's feet could be ticklish despite him using them as brakes for his car... one of TV's most-famous unsolved mysteries lol
I'm not even sure I'd have made any sort of connection or continuity 'red flag' about the two things, even if two scenes demonstrating them had appeared within the same episode.
