After a disappointing run with Laurence Fishburne, CBS’s “CSI” has just rebounded in a big way with Tuesday night’s announcement that the show has signed Ted Danson as a new series regular.

Don’t let the door hit you on the way out, Larry!

Danson will play a new CSI supervisor. News of Danson’s hiring is a major shot in the arm for the aging “CSI” — the mothership — which hasn’t been the same since Fishburne tried to become the show’s new William Petersen.

The low point came in May, when CBS announced that it was tossing “CSI” from the network’s very best drama time slot: the Thursday 9 p.m. throne, from which the procedural crime drama that started it all presided over the resuscitation of CBS.

For this coming TV season, CBS announced that “CSI” would be shipped to Wednesdays at 10, taking over for Jim Belushi’s canceled “The Defenders.” Ouch!

“CSI” got shoved aside so CBS could give its plum time slot to the new TV drama-series It Boy — J.J. Abrams — and his new drama “Person of Interest,” starring Michael Emerson of J.J.’s “Lost” fame.

Now, with Danson, it looks as though “CSI” might still be the prettiest girl in CBS’s lineup.

Fans of HBO’s “Bored to Death” need not worry — Danson will remain a series regular on that show, too. With any luck, he’s also going to continue to show up on HBO’s “Curb Your Enthusiasm.”

“You can create a new character on the page, but until the perfect actor comes along and breathes life into it, it’s just words,” executive producer Carol Mendelsohn gushed Tuesday — when simply “We’re very excited Ted Danson came along” would have been sufficient.
