The only really surprisingly thing about Dollar Shave Club CEO Michael Dubin's appearance in an American Express ad is that it didn't happen sooner. It's been more than a year since Dubin charmed impecunious razor purchasers everywhere with his amusing starring role in his company's debut ad. He's a born pitchman—for whoever he'd like to endorse. The AmEx spot frankly is a little bland, but it proves that while the man may know his dollars, he has trouble with his cents. Via Co.Create.
