A drunk(probably a Presby) staggers through totin' a gallon of liquor in a burlap sack when he come upon a pond. He says out loud, "I wish I knew how deep this pond was so I could wade it." A frog hops upon a log and begins saying, "nee deep, nee deep, nee deep." He says, "if it's only knee deep I'll wade it." He wades out about 10' and the bottom falls out. It takes everything in him to get back to the bank and in the struggle loses the sack and liquor.
As he's setting there trying to get his breath back, another frog jumps upon that same log and starts saying, "jug a rum, jug a rum, jug a rum." He then said that to the frog,"why you sorry thang. You didn't have to lie to steal it!"
Nee deep and jug a rum are two sounds frogs make..Or that's how they sound to me and others.
