Turns out, there's a much more heroic answer behind it all. According to the Independent, the idea was conjured up by the French company, Bic, who added the holes to prevent people from choking to death if they were to accidentally swallow one.
As explained on the FAQ section of their website, Bic claims, "In addition to help prevent the pen from leaking, all our BIC® caps comply with international safety standards that attempt to minimize the risk of children accidentally inhaling pen caps."
