Big Bird is so two weeks ago.

Tuesday evening's second Presidential debate between President Barack Obama and Republican challenger Mitt Romney saw both contenders hit the floor in a town-hall style meeting at Hofstra University in Long Island, New York -- and the proceedings between Obama, 51, and Romney, 65, were noticeably more spirited and at time combative as CNN's Candy Crowley moderated.

Hollywood celebrities weighed in -- via Twitter, of course -- on the fiery discussion, which touched upon women in the workforce, single parents, immigration, gun control, the recent tragedy in Libya and more.

don't support the president - can't support the rubicon lines he's crossed -but I recognize Romney domestic policies will hurt more people

We had a really good presidential debate tonight, and I hope every American is energized to get out and vote in three weeks. I also just want to give a quick thank you to everyone who supported Bristol & Mark. I know how much they appreciated the support. Now Bristol can head home just in time to enjoy Alaska's new fallen snow!

It took 10 years to build the 9/11 memorial and yet Obama was expected to rebuild America in 4 yrs

Please vote obama so Romney doesn't make us all go to sunday school. And: @JohnnyBNerdy not as simple as that Johnny. But I'm happy to pay more taxes to help all.

This isn't so bad for Romney. He can easily win this without single moms, immigrants, the middle class or all women. #debate

Romney's plan for immigrants is to make them so miserable that they will beg him to self deport #current2012
