Kinda like ducks and geese. A guy gave me two ducks and lack for a better name I called them goose and Goose . Worked out Ok until the same guy gave me two Geese, so I just had to call them Duck and Duck.People started calling up saying that the goose was running down the road. Now you wonder if duck was really running down the road or Goose and which one. Really gets confusing not knowing if a car is going to run over Goose or Duck and which Duck or Goose. Guess it really does not matter, so I am going looking for a SNAIL. Might have some luck there.
