Usage of .co.ck
.co.ck has been used as a humorous domain suffix because of its similarity with the English vulgarity "cock":
 * In the British sitcom Nathan Barley, the principal character registers his website, "trashbat", in the Cook Islands simply so that it has the suffix, which he always pronounces "dot cock."
 * One of the payloads of the MEMZ trojan causes a user's computer to open satirical Google searches under "Google.co.ck"
