You always knew this was the case

Exploring the Hostility of Things:

"During some research into the relation between periods of the day and human bad temper, Clark-Trimble, a leading Cambridge psychologist, came to the conclusion that low human dynamics in the early morning could not sufficiently explain the apparent hostility of Things at the breakfast table - the way honey gets between the fingers, the unfoldability of news-papers, etc. In the experiments which finally confirmed him in this view, and which he demonstrated before the Royal Society in London, Clark-Trimble arranged four hundred pieces of carpet in ascending degrees of quality, from coarse matting to priceless Chinese silk. Pieces of toast and marmalade, graded, weighed, and measured, were then dropped on each piece of carpet, and the marmalade-downwards incidence was statistically analysed. The toast fell right-side-up every time on the cheap carpet, except when the cheap carpet was screened from the rest (in which case the toast didn't know that Clark-Trimble had other and better carpets), and it fell marmalade-downwards every time on the Chinese silk. Most remarkable of all, the marmalade-downwards incidence for the intermediate grades was found to vary exactly with the quality of carpet."

Your toast knows what kind of carpet you have.
