What has "ock" in its name and is gigantic? No...wrong, cannot believe that's where you took that question. The answer is clearly John Hancock's gigantic signature on the Declaration of Independence. The man had stones, much bigger ones than you or I for that matter. For that reason, this big old, ultra-classic American flag bandana is named after our boldest founding father. Made of 100% polyester (John Hancock's favorite material).
