Judging by the traffic trends on this blog, it seems the only thing more enjoyable than a brilliant, uplifting, inspirational marketing success is a horrible, embarrassing, cringe-worthy marketing blunder—otherwise known as the big brand fail.

At the link below, we've compiled 20 of the most notable brand fails from 2012—a nice dose of ad-enfreude to fill your evil rubbernecking hearts with joy. Just be glad it wasn't you. And try to learn a lesson from the Harvey Nichols model above and refrain from pissing yourself with laughter. It's not a good look.
