What would you say to an amateur chef who baked a cake following a certain recipe only for everyone who ate a slice to fall ill quickly afterward? Being such an enthusiastic baker, they bake the same cake a second time just a few weeks later, again following the same recipe, but this time with one or two slight adjustments. Unfortunately, the result is the same—everyone who eats the cake soon ends up feeling sick.

The cake baker repeats this more than two dozen times, always modifying the recipe a little, but the basic ingredients remain more or less the same despite the fact that their guests throw up every time. Of course, there's no way such a thing would happen. The cake baker would soon realize that there is a major problem with the recipe and throw it away.
