"Mooses" is a "dual" word; the triple is "meece" and the true plural is "meeces". Thus:
1 Moose
2 Mooses
3 Meese
4 or more Meeses.
"Love to eat them meeses;
meeses what I love to eat.
shoot they furry heads off;
nibble on they legs and feet...."
Dang, went and made myself hungry for a mess of moose liver and onions.
