argyria

A condition in which a person's skin literally turns blue from using too much colloidal silver or overexposure to salt compounds. The blue skin is usually permanent.

The nickname for that man that has argyria is Papa Smuff. We thought that the woman was having a stroke but she was blue because she has a condition called argyria.

Did you see that blue man?

Yeah, he has argyria just like Papa Snurf had.

Weird.
