Some celebrity product endorsements are such natural fits that we have a hard time envisioning the product without the celebrity’s face smiling next to it. Think of Michael Jordan and Nike NKE , or Brooke Shields and Calvin Klein. Or Fabio and I Can’t Believe It’s Not Butter.

Then there are other celebrity endorsements, which attract consumer rage like a moth to a flame. The reasons vary – bad taste, tone-deaf celebrity choice or an erupting scandal. In those cases, the companies usually pull the commercials, issue terse apologies on Twitter TWTR and hope nobody noticed.

Well, at Fortune, we noticed. So join us as we take a look at some good celebrity endorsements that went bad.
