George Clooney, Hugh Laurie Unite for ER 'Reunion' Sketch on Jimmy Kimmel

Is there a doctor in the house?! (Two, actually. And they both look oddly familiar.)

George Clooney and Hugh Laurie stopped by Jimmy Kimmel Live! on Tuesday for “an ER reunion… sort of!” The two actors appeared as their respective doctor characters — Clooney as ER‘s Doug Ross and Laurie as House‘s titular pill popper — to offer their medical services to Jimmy Kimmel.

The sketch was originally introduced as an ER “reunion,” but because none of Clooney’s co-stars were available — Julianna Margulies is filming The Good Wife, Noah Wyle has “Taco Tuesday” plans with his family and Eriq La Salle has jury duty — Laurie was forced to pitch in.

Also, you’ll be happy to know that Kimmel survived the procedure, which required Clooney to spit a little “Rapper’s Delight”; Laurie took care of the choreography.
