On last night's premiere of 'I Am Cait,' Kanye met his mother-in-law for the first time post-transition.

Kanye wanted to express his admiration for Caitlyn Jenner, but a simple "You're awesome" or "Hell yeah, Caitlin" wouldn't do. Oh no, not for Kanye. He wanted Caitlyn to know just how important of a figure she is, and of course, what kind of praise from Yeezus doesn't invoke the entire history of human existence? At a meeting at Jenner's home, West told Jenner:

I think it's one of the strongest things that have happened in our existence as human beings that are controlled by perception.
