WATCH: George Clooney & Hugh Laurie in ‘ER Reunion’ on ‘Jimmy Kimmel Live’

Come for the Clooney reprising his role as Dr. Doug Ross on ER. Stay for the Clooney rapping to The Sugarhill Gang.

Jimmy Kimmel has enlisted George Clooney and the cast of ER to reunite on Jimmy Kimmel Live almost seven years after the show aired its final episode in April 2009. This moment is an ER fan’s dream come true.

Jimmy is on the operating table playing the patient, and Clooney enters to the expected applause. When he tries to act out the scene with his old cast members, he finds that he’s the only one in the room trying to spew medical jargon. Jimmy breaks character and repeatedly “comes to” in order to fill Clooney in on why he’s flying solo in the skit.

So why couldn’t Clooney’s former ER Cook County Medical Center co-workers join him for this long-awaited cast reunion? Everyone was really just too busy. Julianna Margulies was shooting The Good Wife. Noah Wyle was spending Taco Tuesday with his family. Eric La Salle had jury duty. Sherry Stringfield couldn’t get an Uber. Anthony “Tony” Edwards was at SoulCycle.

The underlying joke is that perhaps Clooney’s career is the one needing resuscitation if he’s the only one who was free enough to make it to Kimmel’s taping.

Clooney is saved by the appearance of Dr. Gregory House, played by Hugh Laurie, who dusted off his American accent once again. The House M.D. actor has what is perhaps the best line of the sketch, when peering under the hospital blanket at Jimmy’s little Jimmy. He says, “I don’t do microsurgery.” Clooney and Laurie have some fun with it and bust into laughter a few times, making the skit all the more endearing. The actors struggle to regain their former characters’ command of medical terminology. Laurie is pretty proud of himself for remembering that “BP” stands for blood pressure.

Not content to let Hugh Laurie have all the good parts, George Clooney attempts to save Jimmy, now in cardiac arrest, by performing “Rapper’s Delight” while doing chest compressions. “I used hip hop to save his life.”

We want to see Hugh Laurie and George Clooney work together more in the future! Laurie may be the only actor in Hollywood not appearing with Clooney in Hail, Caesar!
