When Mitt Romney cited the "Seinfeld" character George Costanza at the Republican debate Wednesday night, he probably did not expect any feedback from George himself.

Enter Jason Alexander, best known for his role as George on the wildly popular sitcom, who took to Twitter to respond, somewhat caustically, to the former Massachusetts governor.

Romney's "Seinfeld" reference came as he was introducing himself at the debate in Mesa, Ariz. When the audience began clapping during his opening remarks, Romney said, "As George Costanza would say, when they're applauding, stop."

"Thrilled Gov. Romney enjoys my old character," Alexander tweeted. "I enjoyed the character he used 2 b 2. If he'd embrace that again, he'd b a great candidate."

Romney was referring to an episode in which George expresses frustration that he can't keep his coworkers laughing at office meetings.

"I had 'em, Jerry. They loved me," George says, adding, "I can usually come up with one good comment during a meeting but by the end it's buried under a pile of gaffes and bad puns."

"Showmanship, George," Jerry advises. "When you hit that high note, you say goodnight and walk off."
