Honestly I think the biohazard tie mentioned in the article isn't so bad, since presumably it's warn by someone in the field who will be surrounded by others of the same field, so I don't think anyone will be tricked into thinking the necktie itself is a biohazard. I actually think the biohazard necktie is kind of funny, in certain circumstances (maybe not if worn by my doctor, but instead by someone giving a keynote speech about biohazardous material)

The lunchboxes, water bottles, and helmets on the other hand... that's just absurd.
