Bob Garfield's analysis at the bottom of the list is also excellent. (I love the phrase "savory cardiovascular time bombs," used to describe McDonald's fare.) Also, be sure to check out the other items in the sidebar on the right -- there are all kinds of interesting factoids you can use to impress your friends and win fabulous prizes!
While I'm making recommendations, I'll go ahead and say that "Dirtbag Lunch" might be my favorite print ad of all time. "Dirtbag Twister," which I mentioned in class, is also high on the list. (The sleeping guy in the photo is actually MSU alum Jeff Wogoman, who's now Cloudveil's director of marketing. He got the job when the photographer at the shoot determined that the professional model they'd hired was too good looking to be plausible as a couch-surfing climbing bum.)
While you're poking around and being impressed, you might want to look at all the work done by Alex Rice -- the art director behind the dirtbag campaign. Well, this probably isn't everything he's done, but it's a great little gallery of promotional ideas.
