Adrants has pointed me toward some very nifty banner ads for Zippo.
As described by Adrants: "It's not often online banners excite. Gone are the days a banner would evoke anything other than "Will that friggin' thing stop flashing?!" But Pittsburgh agency Brunner has created an ingeniously inventive banner campaign for Zippo which makes humorous use of the product's primary function."
Check them out here, here, and here. My favorite is the first one. I think it's a pretty cool execution of a fairly tired ad medium. That is, if you wanted my opinion on the matter.
