Eminem, whose next album was teased on the show, also made an appearance.

Dr. Dre, Snoop Dogg, 50 Cent, and Eminem stopped by Jimmy Kimmel Live! to star in a hilarious sketch parodying Grey’s Anatomy.

Entitled Dre’s Anatomy, the sketch sees Kimmel admitted to a hospital for a colonoscopy, only for the nurse to discover that the late-night host doesn’t have a penis. Dre double-checks and struggles to find anything, so he invites Snoop Dogg to come in and take a closer look with his magnifying glass.

That yields no results, too, so they bring in 50 Cent, who brings in a telescope. As the sketch reaches its end, the medical equipment slowly morphs into the beat for Dre’s “Still D.R.E.” Eminem also shows up in a preview for a show entitled EM, which could be a nod to ER.
