Peanut Perfection

Peanut Perfection was a product sold by Millingdale which contained nuts. As stated on the disclaimer page of their website, they refused to say that the product "may contain nuts" as they believed that their customers weren't stupid, and were, according to tests, 37% smarter than people who ate other ice cream.

Behind the scenes
Although it would presumably be an ice cream, it is not actually stated whether this is the case in Disclaimer.
