How I Met Your Mother is celebrated for its heart, humor, and narrative structure. The series is a story that the main character Ted, in the year 2030, is telling his children about how he met their mother. Since the events that he's describing happened decades ago, Ted is an unreliable narrator who makes many continuity errors. Cop out? Some fans think so, which is why many of the following plot holes are blamed not on Ted but on HIMYM's writers. These are the biggest plot holes fans found in the hit series.
