That challenge was annoying because of the terrible spec. In addition to the "around 1/2 lbs" spec, it falsely claims that length and weight are metric (they are not), and it spells it "impostor" in the specified output, but expects "imposter". Both spellings are used in the spec. Frustrating.
However, students will learn not to trust the spec, so I suppose that's a valuable lesson.
