John Travolta and Robin Williams find themselves in cold water when they break into the zoo — all in the name of family -- in their new comedy 'Old Dogs,' in theaters November 25. Watch the exclusive clip, featuring a hilarious Air Supply lullaby by Seth Green! Justin Long also makes a cameo in a separate clip from the movie, in which Travolta and Williams play two best friends whose lives are turned upside down when they are unexpectedly put in charge of six-year-old twins (John's daughter Ella Bleu Travolta and Conner Rayburn). Matt Dillon, Lori Loughlin and John's wife Kelly Preston also star, making the film a true family affair. Watch ET for more with the stars of 'Old Dogs'!
