As the adage goes, you have to kiss a lot of frogs before you can find a prince. And Ted Mosby certainly went through a lot of frogs. Ted ended up dating a whopping total of 38 women on the show before he met the one mother of his kids.
If the kids on How I Met Your Mother never seem to age, it's because they don't. All of the kids reaction shots for the entire series (yes, even the show's ending) were filmed during the first season. Actors David Henrie and Lyndsy Fonseca knew how the series would end and kept it a secret the entire time.
Barney is known for being a suave ladies' man, but did you know he was almost played by someone now famous for playing an awkward nerd? The Big Bang Theory's Jim Parsons was nearly cast in the role of Barney. Looks like he did alright for himself anyways!
Barney is known for his love of magic on the show. But many people don't know that this character trait is copied from Neal Patrick Harris, who played him on the show. IRL, Harris loves magic so much, he's even been the President of the Board of Directors at the Magic Castle in Los Angeles.
On the show, Marshall and Lily rarely kiss. That's because off the show, actor Jason Segel was a smoker and actress Alyson Hannigan hated the smell of cigarettes on his breath so much that she asked not to kiss him on the show.
Alyson Hannigan was pregnant in real life during the fourth season, but Lily wasn't on the show. So the actress' growing belly was disguised on the show except when Lily won a hot dog eating contest and her baby bump was used to show how much Lily had eaten.
The show had many notable guest stars over the years, including Britney Spears and Regis Philbin, but the one celeb that the cast freaked out over most was Project Runway's Tim Gunn. He played Barney's personal tailor, and reportedly, everyone on the cast wanted his autograph!
Both Marshall and actor Jason Segel have something in common - they both won a high school slam dunk contest. Segel played on his Los Angeles high school's basketball team with future NBA player Jason Collins.
