The BF and myself were doing some grocery shopping earlier and came across these:
Said boyfriend looked at them and went "what are those?"
To which I responded (because I am so helpful): "wisps."
Prompting him to say: "This is what happens when night elves die."
Which made us both laugh, because we're nerds. Also it's funny to think of an alliance raid wiping on the Lich King or something and having a bunch of tiny, disposable toothbrushes clattering to the ice.
