“Friends” sorta invented the ‘Mannequin Challenge’ 13 years ago. There’s a deleted scene from Season Eight where Rachel is trying to get her baby Emma to crawl, but she won’t so she has everyone freeze so baby Emma isn’t distracted. Phoebe walks in and joins in without knowing what they’re doing, grabs a bowl . . . freezes . . . and says, quote, “Who’s painting us?” That’s it.
It never actually aired on TV. But it’s been on DVD for years.
