NEW YORK (AdAge.com) -- It's certainly not unusual that a stand up comedian like Tim Washer would be producing absurdist viral videos. What is surprising is that the IBM communications executive is doing so for his straight-laced corporate employer. He appeared at a Business Development Institute seminar on corporate social media practices last week. There, he championed the cause of creative absurdity in corporate marketing. And he warned the audience that fear and rigid thinking were the greatest obstacles to their companies' social media success.
