Correct the "bi" already means there are to of them. Kind of like saying you're riding a pair of bicycles. Just one of my pet peeves.
point taken.
how about "a pair of pliers"? 'pliers' is plural, but we are talking about a single object, and "pair" seems redundant...
pair of pants?
regardless, i'll make an effort to use the term correctly.
and of course, it is my duty to point out that a post correcting somebody's english should have 'two' spelled correctly.
