Here's an ad that actually got Snickers into quite a bit of hot water, though if you don't take it too seriously, it's actually very amusing.
The ad opens with a couple guys working on a car, something many consider to be a relatively masculine affair. One of the guys pulls out a Snickers, and starts eating it. Noticing the delectable treat (but not the guy eating it), the other fellow goes to town on the opposite end, Lady in the Tramp-style. The two men then share an accidental moment of unintended intimacy — recoiling with horror, one says, "I think we just accidentally kissed," followed by "Quick! Do something manly!" For some reason, doing something manly means opening your shirt and ripping out a handful of chest hair.
Whether or not this is how most men behave (it's not, especially the chest hair part) isn't really the point. The ad is funny because of its stupidity, but it also works for Snickers by saying the candy is so good this might happen (though if you pay attention to who's eating a foot in front of you, it probably won't). The company took a lot of flack over the ad, which was ultimately pulled off the air, but … come on. You laughed at it, too. It's okay to admit it.
