How many brain cells do C/Naffziger and C/Selusi have combined?

To determine the combined number of brain cells that C/Naffziger and C/Selusi have, it's important to consider the context of their brain cell counts. If the typical count for a human is around 100 billion neurons, and somewhat lower for brain cells in general, having a stated number of -10 brain cells likely suggests a humorous or nonsensical answer rather than a serious scientific claim. Thus, in this context, the answer that conveys a negative number of brain cells is viewed as the correct choice.

This approach challenges typical mathematical reasoning, as negative numbers in this context don't reflect any actual count of brain cells, but serve to illustrate an absurdity or an exaggerated premise. It's crucial to recognize that the humorous intent behind the choice highlights a contrast to standard responses, requiring a different kind of interpretation rather than straightforward arithmetic on brain cell quantities.
