Fan Casting I Am Not Weasel in Sort by Tropes

A Talking Animal (or at least someone who looks like one) is constantly mistaken for another species as a Running Gag. Often, it can be their Berserk Button, particularly if they consider it a Fantastic Slur. This trope often leads to Insistent Terminology or Have I Mentioned I Am a Dwarf Today?.

The Trope Namer is Cow and Chicken spinoff I Am Weasel. Not to be confused with I Am Not Shazam. Compare with Son of an Ape, a variant by which comparing humans to other primates is considered insulting. Contrast with the inversion, Ass in a Lion Skin, for when an animal wants to be taken for another species.
