Have you ever had one of those moments where you hear a phrase, or a fact, that you've never heard before in your life, and then hardly a moment passes before you see it somewhere else? And you think to yourself, "How come I have never come across this before in my entire life, and now it seems like it's absolutely everywhere?"

It happens fairly frequently to me and it's just happened again. Yesterday I read an article by Peter Barron, editor of Newsnight, about podcasts, which included this excerpt about the current number one podcast on iTunes:

It's something called Kitcast. Kitcast is, according to the blurb, "a ten minute weekly videoblog covering the world of sex". Each episode, it goes on, is "hosted by a lingerie clad (non-nude) hostess Ms Kitka" - a little red box warns of explicit content.

Ms Kitka. "Interesting name, that," thought I. "No idea where it comes from though. Probably Russian."

Fast forward to this morning and I'm trying to find some decent television to watch (see previous post). The best Sky One can come up with is Supervixens, an exploration of comic book superheroines and the actresses who've appeared as them in the movies and on smaller screens. I only catch the very end, which is about Catwoman. I learn that at least one incarnation of Catwoman had an alter ego known as Ms Kitka!

I go 21 years and 7 months never having once heard the name "Kitka", and in the space of 24 hours I know it serves both as a disguise for Catwoman and the nom de pod for some sex-obsessed woman. Fascinating.
