George Clooney was excited to be reunited with his former ER co-stars on Tuesday's episode of Jimmy Kimmel Live. However the actor, who starred in the medical drama from 1994 to 1999, was left disappointed when it emerged the host had trouble getting the actors back together for the skit.

Playing a medical patient in the sketch, Jimmy broke the news that Julianna Marguiles was busy filming The Good Wife, while Noah Wylie had a Taco Tuesday. However fellow medical drama alumni Hugh Laurie stepped in to help save the day for the ultimate ER-House mash up.

For one night only George's character Dr. Douglas Ross joined forces with Hugh's House alter ego Dr. Gregory House to perform CPR on Jimmy, who went into organ failure on the hospital bed.

"Dr. Ross this isn't working, you got to give him the rapper's delight!" Hugh told George, who promptly began performing the Sugarhill Gang's hit Rapper's Delight.

"I said a hip hop, the hippie to the hippie, the hip hip a hop, and you don't stop, a rock it, to the bang bang boogie, say up jump the boogie," he rapped while pumping Jimmy's heart to the rythym.

George was catapulted to fame on the medical drama and he previously reminisced about the moment he realised his life had changed in an interview with Esquire. "Thanksgiving [of 1994], I was walking in New York with my buddy Ben, and some guy goes 'Hey George!' I'd been recognised before but it was always my character's name.

"The fact the guy knew my name? I remember Benny looked over and he goes, 'You just got famous, dude.' And I was like, 'I just got famous!' It was exciting."
