- Where did we learn this canon fact? - Besides the dual stream confirmation in Discovery, I believe it’s in Enterprise that we first learn that Klingons have two of every organ. - And I believe I recall a throw away line of confirmation (of the double organs) in Picard. - I’m honestly surprised if Lower Decks hasn’t dealt with the topic yet. - Klingons have two of every organ. - The Skin is an organ, not just an organ but the largest organ. - That explains the facial folds. - Not canon, but there was a fan theory that the changes occurred after the tribbles were transported aboard the Klingon ship in TOS. - They retconned the TOS Klingons in Enterprise - https://en.m.wikipedia.org/wiki/Affliction_(Star_Trek:_Enterprise) - TIL - Thanks 
 
 
- And also why mother Klingons carry their young by gripping the loose skin on the back of their necks… no wait, I’m confusing Klingons with something else, aren’t I?

- “Klingons are like onions.” - “You mean they smell bad?” 
 
 
- *cannon - It’s in the title of the post. Canon would be if something would be verified in the Star Trek universe. Which this is, sure, but think about it: it’s much more likely to be a comment on the girth and power of Klingon instruments
