Hi, I'm Frederick

Takei pierced Shatner's nipple while fencing like crazy, he also got around the set poking everyone's butt cheeks, almost got in a fist fight because of it (according to Shatner)

There's an audio interview between Roddenberry and Sarek (Mark Lenard in character), where Roddenberry doesn't even blink before asking about Sarek's sex life with Amanda.

James Doohan lost a finger during WW2

DS9 writers managed to write Nana Visitor's (Kira) pregnancy into an episode. The father is Alexander Siddig (Bashir). The kid name is Django (if I'm not mistaken), and he's handsome like his father.

In some interviews, Andrew Robinson (Garak) made clear he was 190% gay for Siddig

During the first TOS season, Roddenberry was married to a woman called Eileen... Nichelle Nichols and Majel Barret were his side chicks (rumor), when Nichelle found out about it, she left him and almost left the series as well.

The first interracial kiss was supposed to be between Nichelle Nichols and Leonard Nimoy, but, beside the fact that some folks thought that impact would be better if she kissed a human character, Shatner called dibs on her kiss (according to Ms.Nichols)

One day, the makeup team put Vulcan ears on Leonard Nimoy's son, Adam. They filmed and even put a photo in a newspaper, its adorable.

AND THIS! (and the several gifs I have of Shatner kissing Nimoy, but I'm running out of room)

Nimoy got stuck in a garbage can and needed rescuing

But my favorite least known fact is that the gold command uniforms were not gold, but green. A mix of the fabric, the stage lighting and the color bias of the film made them appear gold but in real life they're very much green. That's why the wrap and dress uniform are green. Here's the original comics where the uniform is actually pictured true to color, and info from startrek.com explaining why the color shift happened
