For example, here's how Woot describes itself in the FAQs:
Woot.com is an online store and community that focuses on selling cool stuff cheap. It started as an employee-store slash market-testing type of place for an electronics distributor, but it's taken on a life of its own. We anticipate profitability by 2043 – by then we should be retired; someone smarter might take over and jack up the prices. Until then, we're still the lovable scamps we've always been. But don't take our word for it: see what the online community has to say at this Wikipedia article.
Woot (now owned by Amazon) is definitely a marketing phenom best experienced by clicking around its site. And for another laugh, see The Street's tongue-in-cheek story...Happy new year!
