George Clooney and Shannen Doherty

There are few things better than reconnecting with old friends. Except when they're now-famous old friends on TV.

We're heading into a surefire winner of a doubleheader this spring: Megastar George Clooney's Dr. Ross will check back into "ER" tonight as the long-running hospital drama prepares for the big goodbye on April 2, and Shannen Doherty's bad girl-gone-good Brenda will resurface -- with child in tow? -- on "90210" for its season ender.

But not all reunions have resulted in heartwarming nostalgia. We rate history's biggest TV comebacks, from David Duchovny's triumphant return to "The X-Files" to Clay Aiken's awkward fan encounter on "American Idol."
