You know how sometimes when you buttered something, there might be a little dot of butter left on your butterknife? Some people just wipe it off on a napkin, some people put it back (ew) and some people just eat the little dot of butter, because butter isn't horrible since you just put it on your bread, too. Now, consider scale, too. To the HAMSters, a slab of butter is what a dot of butter is to you, and they're definitely not going to wipe it off or put it back.
