why must you yanks use the plural "legos" for lego? the plural of lego is "lego". if you wish to refer to more than one lego brick, please use the term "lego bricks". and FYI, the "lego men" you speak of are correctly referred to as "minifigs".
I'm sorry, but... Why is this relevant?
In any case; words are always evolving.
Legos can be the plural if people choose it to be.
Lego men is also an acceptable term for minifigs, as that is just what the company has chosen to name them.
If people want to say lego men, they can.
Oh, and please use proper capitalization when you post.
