"Oh, ho!"

"Oh, ho!"  How in the world would you translate that?  Marash Girl exclaimed, "Oh, ho!" this morning when things seemed to be going awry (the napkins wouldn't fit in the napkin holder after numerous tries . . .) but this expression has music attached to it and situations in which the expression would fit or would not fit.  Do any of you remember the Armenian old folks saying, "Oh, ho!"?  Do old folks say, "Oh, ho!" in other cultures?  Help Marash Girl out here, folks!
