From Zatanna #2, one of the great throwaway gags of the series: Zatanna asks her friend if she’s seen the Phantom Stranger lately, and she’s told “The last time he was here, I asked him to pick me up a loaf of bread from the corner deli. That was two years ago. He certainly loves to wander.” And then, at the end of the book, he returns:
(Sadly, he doesn’t actually do anything in the next issue. Mind you, I’m not entirely sure what he does anyway, though he does do it with a certain amount of flair. I don’t know why, but the Phantom Stranger is just cool, and I’m strongly considering picking up the DC Showcase: Phantom Stranger volume this week.)
