Josh Radnor recently opened up about a How I Met Your Mother memory that fans still bring up on set walkthroughs and blooper compilations alike. During a candid chat, the actor slipped into storytelling mode about his years playing Ted Mosby alongside Neil Patrick Harris. What followed was a nostalgic detour into one specific scene involving a car nobody on set actually liked. The anecdote captures exactly why that particular cast dynamic still gets talked about.

While Radnor reminisced about scripted chaos on set, one improvised moment stood out as a defining piece of Barney Stinson's comedic legacy.

Josh Radnor confirmed that one of Neil Patrick Harris' most memorable Barney Stinson moments started as an unscripted flourish rather than something written into the episode. The scene required Harris to express hatred for a Pontiac Fiero, and he took the moment somewhere unexpected on set.

"I am sure this is on the blooper reel, but he had to say he hated the Fiero," Radnor said on Half the Picture podcast.

"He did this thing where he went, 'Love it.' Then he turned to the wall, whipped his head around, and said, 'I hate it.'"

That whiplash delivery, Radnor explained, became one of the clearest examples of Harris turning a small line into something unforgettable.

Beyond that single scene, Radnor used the same conversation on Half the Picture to describe what made working opposite Harris so distinct across nine seasons. He called his former co-star a remarkably skilled comedic performer, someone capable of delivering the same joke three separate ways and finding a fresh angle each time. Radnor also noted that Harris possessed an instinctive command of comedic timing that felt almost mechanical in its precision, something he admired rather than tried to replicate in his own more restrained approach to Ted Mosby.

As those set stories keep resurfacing online, plenty of newer audiences are left wondering where they can actually revisit the series today.

Where to watch How I Met Your Mother in 2026

How I Met Your Mother departed Netflix on December 3, 2025, closing out a run that made all nine seasons available to a global audience for years. Viewers in the United States looking to continue the series can now find it on Hulu, which picked up the licensing rights following the Netflix exit. Audiences in the United Kingdom and other international regions can access the sitcom through Disney+, keeping Ted Mosby and the rest of the MacLaren's Pub crew within reach despite the platform change.

For those who prefer a more permanent option outside subscription platforms, digital purchases remain available through Amazon Video and Apple TV, allowing full ownership of every season. Physical media collectors can also track down DVD and Blu-ray box sets through retailers such as Amazon. Between the platform shift and Josh Radnor's resurfaced anecdote, interest in revisiting the show and its most memorable bloopers shows no sign of slowing down.
