So that silly pair of purple-clad superheroes, The Wonder Twins, are coming to Smallville this Friday. I can think of worse things that could happen to the show: Kristin Kreuk could return (shudder), for example, or Clark's bare chest could start to sparkle in the sunlight, ala Edward Cullen. Now that would be truly terrible.

But Zan and Jayna nerding up the joint? Sounds like fun to me.

Being a fan of the veteran superhero series, I'm not embarrassed to say that I'm looking forward to seeing the live-action Twins bump fists this Friday. (I wouldn't even mind a cameo from everybody's favorite blue monkey, Gleek, but sadly I don't think that's in the cards.)

Even when I was a little kid, there were some things about the Super Friends (or Superfriends or Superamigos, or whatever they were calling it) that didn't sit right with me. Maybe it was because the confluence of superpowers all in one place just boggled my young mind. Maybe it was the mysterious change from Wendy and Marvin to the Wonder Twins that made me scratch my tiny noggin. Not sure. But those mysteries continue to fascinate me, even into adulthood. It's just that those mysteries are more sophisticated:

1. How did the Super Friends have time to hang out at the Hall of Justice? Every one of the SFs lived in different parts of the country: Batman and Robin were in Gotham City, for instance. So, did B&R commute from Gotham to Metropolis a few times per week? Did they use the Bat Plane or the Batmobile most of the time? Did they claim the mileage on their taxes?

Welcome to TV Squad Lists (formerly 'The Five'), a feature where each blogger has a chance to list his or her own rundown of things in television that stand out from the rest, both good and bad.

In honor of my own twins, Jason and Victoria, who turned the Big One on April Fool's Day (no fooling), here's a not-so-comprehensive list of television's most famous twins.

Mary-Kate and Ashley Olsen -- Oh please, like they wouldn't be at the top of this list! I can't remember a set of television twins who went on to become such huge media moguls. You scoff at me? Well, when is the last time you heard about Christopher and Clayton Griggs, who portrayed Nelson Tibideaux, son to Sondra and Elvin, on The Cosby Show? I rest my case. Anyhowsit, due to some savvy investing and product placement, these two girls are worth something like a kazillion dollars (ballpark estimate -- I lost count after a jazillion). Now, if they could only stay out of the tabloids for five minutes to enjoy all of their success.
