Feeding your marketing manager to the sharks may not be the most palatable way of proving a point. And by the look on the face of Melissa Wilson (left), fish marketing manager at Princes Foods, we think she was going well beyond the call of duty.

If that's what Princes does to its staff when things go well, who knows what it'll do if it ever slips a few percentage points. {{COUNTERPOINT }}
