The news that Tom Bergeron and Erin Andrews would not be returning as hosts of Dancing with the Stars in Season 29 was the announcement heard around the world — a jaw-dropping upset of the DWTS natural order. But it was hardly the first shocker in the history of the show. 

Over the course of its 15-year run (and yes, you're that old) ABC's reality dancing competition has been the home base for plenty of other shocking moments, from unbelievable castings to gruesome injuries, feuds, wardrobe malfunctions, and heartbreaking live confessions. On its face, DWTS should be a pretty simple and straightforward show: celebrities dance, judges judge, viewers vote, and someone is crowned winner. But it gets more complicated than that — really complicated. And just think, the broken bones, public spats, and nip slips within this gallery are only what we see; the drama that goes on behind the scenes must be next level! 

Until that tell-all expose comes out, we can ooh and ahh over all the juicy, tawdry, and sometimes sad moments over the years that truly left us speechless. Here are the 25 most shocking moments in Dancing with the Stars history. Do you remember them all?
