Jason Alexander Debuts Hair On 'Harry's Law'

For "Seinfeld" fans, it's the height of irony that Jason Alexander now has hair.

And now Alexander is debuting his little friend on the aptly (unfortunate? ) named NBC drama, "Harry's Law." On October 19, Alexander will guest star as an ex-high school biology teacher trying to get his job back.

The actor told TV Guide that his "dorky" character would have worn the bald head better.

"The biggest image people have of me is from the reruns of 'Seinfeld', and I'm just trying to put my hair back to the way it was then," he says.

Well, not quite.

"I'm waiting for Jerry [Seinfeld] to rag on me. When he sees me with this, I'm sure I'll get an email saying, 'What the hell are you doing?'"
