For a little taste of non-traditional advertising, Canada’s Yuzu Sushi gives us…spare tire advertising. Yes, spare tire advertising. Perhaps they figure assvertising was a bit too…oh…in your face whereas the ass end of a car would be less offensive and, well, more effective. After all, most people stare at the ass end of a car much more often than they stare at the ass end of a woman lifting her skirt so you can see the branded underwear she’s wearing.
