The Odd Sock is a fictional character. He therefore did not grow out his purple toenails for two months before quality testing, as he does not have purple toenails. He did not wear the socks while bike riding, playing tennis, running a marathon, or synchronised swimming, as he did not indulge in any such activities. Needless to say, he didn't wear them for two months straight without a wash. To reiterate, he is the fictionalisation of a real person (who has asked to remain anonymous). The Odd Sock thanks you. (The person, not the character. Although the person is quite a character.) Thank you. Cheerio.
