I've been rewatching TOS recently, and I noticed that Chekov's hair had a mind of its own for a while. I took a few screenshots, looked up the story behind it, and made this really quick for anyone like me who wasn't aware.
Roddenberry wanted Chekov to bring in the youth audience, so they gave him a wig to try to make him look like he's from the Monkees or the Beatles... absolutely hilarious.
I don't blame you. I'd be laughing my ass off too. The Monkees though... I see where they were trying to go. They got close but missed by a few parsecs.
Hey hey we’re the Monkeeeeees, Where can your nuclear wessels be found?
