When my mom was a kid, my grandma told her not to share hairpieces as she might catch "dandruff". "Dandruff" was my granny's word for lice, so my mom and 11 of her other syblings used to believe that dandruff was contagious. Even when my mom was older and knew that dandruff-covered hair things couldn't make your scalp flake, dear old Grandmother was contradicting logic with weirdness.
