1. Caitian Threesome
Star Trek memorably showed Kirk copping off with an alien in its opening reels, and true to form, Into Darkness isn't much different; we see Kirk engaging in a threesome with what appears to be two Caitians (sisters?), a cat-like species that was first introduced in Star Trek: The Animated Series with the feline crew member M'Ress. Though some have disputed that these two aliens are, in fact, Caitian, it's clear as day to me, especially given that Abrams makes it clear to demonstrate a wag of their tails before Kirk leaves. One of the more playful and overt references in the film, this is one that people can enjoy even if they don't quite know which species it's nodding to.
