jeepers creepers!

A mild exclamation of surprise, astonishment, fear, or delight. A: "I just found out that they want to promote me to General Manager!" B: "Jeepers creeper, Tom—that's great news!" Jeepers creepers, don't sneak up on me like that! You nearly gave me a heart attack!

An interjection of surprise or delight. The equivalent of “no kidding!” or “wow!” depending on the context, the phrase came from a 1938 popular song first sung by Louis “Sachmo” Armstrong in the movie Going Places. The chorus began, “Jeepers Creepers, where'd ya get those peepers? / Jeepers Creepers, where'd ya get those eyes?”
