Monkey Flavor
Some years ago, a friend of mine got married in Connecticut, and a whole crowd of my crowd travelled down for the event. I stayed in E'beth and Hacksaw's hotel room, where I learned that their toothpaste of choice is Tom's of Maine Outrageous Orange Natural Anticavity Toothpaste For Children (who said Mainers were taciturn?). At the time, the product design featured pictures of an orange, a banana, a pineapple, and a monkey. Intrigued, I checked the ingredients list, which explained that the toothpaste features orange, banana, pineapple, and other natural flavors.
Since then, I've generally assumed that the mysterious 'other natural flavors' on ingredients lists refers to monkey extract. And you'll notice that Tom doesn't deny it.
