Talk to anyone who watched the Super Bowl and they will definitely remember the Chrysler commercial with Clint Eastwood. While the classic conditioning in this ad is not quite as obvious as in the Eminem ad, it is still there.
Who is more associated with traditional American grit and determination than Clint Eastwood, From Dirty Harry to Gran Torino, you will almost never see a movie where Clint is not using his gravely voice to intimidate anyone and everyone involved. Couple this with constant relations to football, One of the most loved sports in the nation, and pictures and videos of your stereotypical work-a-day American as well as flags and other patriotic symbols, and you got yourself a whole mess of unconditioned Stimuli that all point to one thing, Chrysler=America.
Traditionally, America is an extremely patriotic country, whether you call it arrogance or pride, there's no denying that the vast majority of Americans love their country despite its quirks and flaws. So, the unconditioned response that Chysler is looking for is that when you see a Chrysler, you immediately think of "'Merica" and patriotism. They want you to feel like buying a Chrysler turns you into the gritty Clint Eastwood figure that will stop at nothing to power his way through the current recession.
You can argue that this ad is a little corny (especially if you've seen the SNL parody, which is hilarious), but you cant deny that maybe even subconsciously this ad is pretty effective. I may or may not have felt the urge to wear an American flag as cape everyday after seeing that commercial.
