Seth: Its gum.
Me: Why did you put gum on your neck?
Seth: When I had gum yesterday, I pulled it out of my mouth real long and put it around my neck to make a cool necklace, a gum necklace.
Seth: Is it PINK?! (rubbing his neck with pride)
Me: Nope its black because of all the dirt thats stuck to the gum, you shouldn't take your gum out of your mouth anymore.
Seth: Oh, ick. (rubbing his neck more vigorously, grossed out) Ok I'll keep it in my mouth next time.
