Shut up. It is too. And I'm not the only one who thinks so.
It's too late to order them and get them out for this year, but Cartouche Press has some purty Cthulhu Valentines that you can get for next year. They've got art by guys like Ash Wood and Christopher Shy, so you know they're gonna be nice. Stock up now so you'll be prepared to tell that elder god in your life just how you feel.
Also in honor of this special day, I'd like to remind you that Boom! Studios is producing a Cthulhu Tales anthology. It's got a Keith Giffen story in it and is illustrated by guys like Andy (Easy Way) Kuhn and Andrew (Fused Tales) Ritchie. Monsieur Ritchie also illustrated one of my chapters in the forthcoming Three Days the Devil Danced graphic novel, so I've got a personal connection with this one.
And finally, my Valentine's Day present to you: Cthulegos! Guest-starring Doctor Who, a Dalek, some zombies, Jedi, Indiana Jones, Dumbledore and maybe Fox Mulder.
