We speak of the outcome of a coinflip being _heads_ or _tails_, which are surely singular nouns in this context, despite being derived from the plural forms of _head_ and _tail_. So when we flip a coin twice and get heads (respectively tails) twice, should we describe the outcome as two _heads_ (respectively _tails_), or two _headses_ (respectively _tailses_)? I feel like you could make a logical case for the latter, but I guess the former does sound more natural?
