Well, what do you know about the distribution of "two dice"?

And my standard complaint: "dices" is a verb. "dice" is itself already plural- it is the plural of the word "die". You mean to say "two dice".

Same as "two shoes". Common usage.

No, it is not the same. "Two shoes", yes. "Shoes" is the plural of "shoe" But not "two dices" because "dice" is already plural. It should be "two dice".

Right. Dice is plural. Are you sure it's a grammar error from the OP and not just falling asleep on the keyboard?
