“Uh-oh” embraces “Here we go again” and “Now What?” and “You never can tell what’s going to happen next” and “So much for plan A” and “Hang on, we’re coming to a tunnel” and “No sweat” and “Tomorrow’s another day” and “You can’t unscramble an egg” and “A hundred years from now it won’t make any difference.” 
“Uh-oh” is more than a momentary reaction to small problems. “Uh-oh” is an attitude—a perspective on the universe. It is a power of an equation that summarizes my view of the conditions of existence: 
“Uh-huh” + “oh-wow” + “uh-oh” + “oh, God” = “ah-hah!”
