What is Happening Here?

Poor Ian.  What happened here?

a)  He was abducted by aliens who inserted metal balls to alter his brain waves.
b)  He ate some bad hamburger that had been injected with metallic steroids.
c)  He fell asleep on the floor in the front room and this is what his drool looks like.
d)  His younger brother and sister were bored and decided to decorate his face with magnetic metal balls.
