You may have seen an uncharacteristically bawdy ad for Crocs on the Internet this week. Well, it turns out it was fake (it was apparently a spec spot from London production company Compulsory), and Crocs isn't happy about it."It is not an authentic Crocs ad," the company says. "We're very concerned by it, because it does not reflect our company values as a global lifestyle brand. No one at Crocs is familiar with this ad; no one at Crocs authorized its creation or appearance. We are committed to portraying the Crocs brand in a positive and respectful manner." This is understandable. Any sexiness scale worth anything would rate Crocs somewhere between dead grandma and Linux conference. Any ad that suggests otherwise is clearly phony.
