Jason Alexander is heading back to NBC. The 'Seinfeld' veteran will appear on the fifth episode of 'Harry's Law' Season 2.

According to TV Guide, Alexander will play Richard, a public school teacher who's suspended after he fails a student. The reason the character handed out an F? The student, Zack, called Darwinism "a crock."

Kathy Bates' Harriet Korn takes the case to court.

Alexander recently made a guest appearance on TNT's 'Franklin & Bash.'

'Harry's Law' premieres Sept. 21 at 9PM on NBC.

On soaps, every now and then the powers that be -- usually the head writer who's overdosed on Red Bull and jelly beans months before -- comes up with the idea of doing a special episode. They'll focus on a single character and think outside the box. Sometimes they hit the jackpot; sometimes they create a clunker. The Young and the Restless offered a very special New Year's Eve episode yesterday and it was a home run.

Headwriter Maria Arena Bell and her talented team, including Hogan Sheffer, decided to put the character of Billy Abbott under the microscope and, as it turned out, Y&R pulled off a great episode.

It wouldn't have worked nearly as well if not for the riveting performance of actor Billy Miller. He rose to the occasion and this could be an award-winner if it's submitted for the next round of Daytime Emmys. If you haven't seen it yet or it's in your DVR waiting to be viewed, be warned that there are SPOILERS ahead.
