Dirt's Courteney Cox to appear on SCRUBS for 3 Episodes

Could this casting be any cooler? Courteney Cox is joining the cast Scrubs for a three-episode arc this coming midseason, playing Sacred Heart's new Chief of Medicine.
Cox's character will "ruffle feathers" in her capacity as Kelso's replacement.
Does one wonder if Courteney feels the desperate need to have say a SITCOM again...anyone,anyone?!?
