In the video, Andy Samberg, Jorma Taccone and Bieber standing in for Akiva Schaffer celebrate the milestone by throwing a bash and — well, we can’t print what else they want to do. Trust us, it's gross.

Natalie Portman reprised her role as an insane, trash talking version of herself to declare, “Yeah I had a baby, but I’m still crazy.”

Jon Hamm appeared as the shirtless sax player Sergio and Michael Bolton sang about Captain Jack Sparrow again.

Justin Timberlake colored himself badd and put a box in front of his pants, while musical guest Usher and host Will Ferrell made their first appearances.

The most glaring digital short missing from the retrospective? “Lazy Sunday,” the second and arguably greatest short in “SNL” history. It’s still all about the Hamiltons, baby.

We’d embed the 100th digital short, but holy moly it’s NSFW. So watch the video here.And if you feel like taking a trip down memory lane, watch the first digital short “Lettuce” below.
