Arguments based on analogies often overlook important differences between the two things being compared. Examples are provided that use analogies in absurd ways by drawing comparisons between unrelated things like a person growing on another like a bacterial colony or having a perfectly oval face shaped like a circle compressed by an exercise device. A further example is given of being as lame as a duck that was literally lame from stepping on a land mine.
