I always thought that the plural of moose was "meese", since the plural of goose is geese. I got the idea of "meese" from the Pinky and the Brain episode "Brain Acres", where they said...
B: Pinky, AYPWIP?
P: I think so, Brain, but if the plural of mouse is "mice", wouldn't the plural of spouse be "spice"?
And then the plural of house would be "hice", right?
