But eagle-eyed fans noticed something a little different about Boyle's new hairstyle, and wondered if the new episodes would see the character's "glow up". One person quipped in the comments: "CHARLES CHANGED HIS HAIRSTYLE??? ARE WE GETTING A CHARLES BOYLE GLOW UP???"

A second person also spotted his new locks, writing: "Boyle's hair??? Ummm HELLO?????" A third fan said: "Joe's hairrrr omg!!", as a fourth wrote: "Boyle. Hair. Me. Love. It."

It's a bittersweet moment for fans because although the new season is back on NBC, it marks the end of the sitcom's run.
