I think we all know now that when Bill Cosby tells you to drink something, DON'T.
Aaaaaand, we're done.
I had a professor who did consumer polling/testing. Sometimes he'd tell us stories. One was about New Coke. When they (blind) product tested it, people overwhelmingly preferred it to the original. When they told them it was a new recipe, they said it wasn't as good. They told Coke this and they shrugged.
For the longest time I thought that line was "Rock and roller color wars," which to be honest still sounds way more interesting.
