Courteney Cox, Alex O'Loughlin, Jesse Tyler Ferguson, OK Go

While hiking in Utah, a man named ZAK ANDEREGG saw an abandoned puppy 350 feet down a hole -- and risked his life to save it! He and his wife MICHELLE are here with the dog, Riley, to share the beautiful story with Ellen. COURTENEY COX knows how to stay young -- or at least keep the men around her young! She's starting a brand new season of "Cougar Town," where she's reuniting with "Friends" co-star Jennifer Aniston! "Hawaii Five-O" is back and better than ever with a brand new reboot. The sexy ALEX O'LOUGHLIN will tell Ellen all about it. OK GO is known for their inventive music videos, and today Ellen has the world premiere of their latest.
