6.) “How I Met Your Mother,” “Last Forever” (2014)
Since this entire show consisted of Ted Mosby (Josh Radnor) telling a story to his children (with Bob Saget as the narrator) about how he and their mother met, viewers were in utter disbelief to find out what happened after nine seasons worth of stories.
In the finale, Ted reveals that the mother of his children passed away six years ago. As it turns out, he ends up married to his longtime friend Robin Scherbatsky (Cobie Smulders).
