The surest sign that you've created a viral juggernaut is that the parodies quickly come flowing in. This will be especially true of Wren's "First Kiss" ad, which is so stripped down visually that it will be easy to spoof. First out of the gate is a British brand with a reason to jump all over this—Snog frozen yogurt. (A "snog," of course, is British slang for a makeout session.) Check out the parody below, and wait for the onslaught of about 5,000 more by tomorrow. Agency: Krowd.
