All of the celebrities from your favorite Saturday Night Live digital shorts returned on Saturday night to celebrate the series' 100th sketch.

The music video starts with a peppy (and soon-to-be confused) Justin Bieber introducing the clip with digital short creators Andy Samberg and Jorma Taccone. The trio launches into song and dance before an all-star cast joins them to belt lyrics primarily about ... well, ahem, you can watch and see for yourself.

Michael Bolton, Jon Hamm, Natalie Portman and Justin Timberlake revive their beloved characters from past popular sketches (think "Jack Sparrow," "The Curse," "Natalie Raps," "Motherlover" and "D*** in a Box").

"Yeah, I had a baby, (what!) but I'm still crazy," Portman raps. "Show my ass respect."

Usher and Will Ferrell also drop lines in the raunchy jingle.
