The Kate McKinnon/Aidy Bryant/Kyle Mooney era of Saturday Night Live has ended.
The three SNL veterans are officially leaving the show, along with Pete Davidson.

This is obviously a big deal, so here's how they said goodbye to the show:
Kyle revived his role as Brad Dates, the long suffering keyboardist of the Treece Henderson Trio.

Aidy did one last Weekend Update segment with Bowen Yang, as two "trend forecasters."

Kate bid farewell to one of her most beloved characters, Ms. Rafferty from the "Alien Encounter" sketches. Her goodbye was the first tearjerking moment of the night.

Finally, the last sketch of the night (and their final sketch on the show) saw Kate and Aidy playing a pair of eccentric middle-aged women once again.

Their commercial for "grey adult pigtails" featured several other cast members and host Natasha Lyonne, and ended with the revelation that they were all in a polyamorous relationship with Richard (played by Kyle).

Finally, they sang a few lines from Joni Mitchell's "The Circle Game," which I can imagine they chose for their last sketch because it's a song about the passage of time.

You can watch the whole farewell sketch (and maybe cry a little bit) right here:
