I used to live near P&G and would do lots of focus groups for their products. My favorite was when they needed babies for diaper and wipe studies - at one point I had 600 Pampers in my garage. I had to save the wet ones in garbage bags and return them to P&G. Crazy but boy did I save money. They really put a lot of research into the most minor things, like the cartoons on the front of the diaper. It was great. I miss it!
