Britney Spears made her second appearance on CBS' "How I Met Your Mother" tonight, and I can't stress enough to the show's writers and producers how little she is needed.

Not that she's been bad. Her second appearance wasn't as tight as her first, and tonight she really came off as a bad actress. No, I never had some thought that she was a comic genius-in-waiting. However, in Britney's first HIMYM appearance, she looked well-coached.

Perhaps I'm not in the mood to be mean-spirited tonight ...

On the other hand, one of the things I really appreciate about HIMYM is how "nice" it is, particularly the story line this week between Lily (Alyson Hannigan) and Marshall (Jason Segel). To raise money for a house expense, Lily decided to sell some paintings.

Long story short, writers went with the cliched storyline of the husband not believing in his wife's talent only to have her prove him wrong. However, writers worked in some sight gags with Ted (Josh Radnor), some terrible red boots and a GCWOK (Gay Couple Without Kids).

And at the end of the show, once Lily and Marshall had secured enough money from her art work to pay for their expense (I won't give the circumstances away ...), he created a site for her to sell more of her paintings. But that's not the cool part.

CBS really created a site called lilyandmarshallselltheirstuff.com with souvenirs from the show for sale to benefit a children's hospital. Television producers are quite eager nowadays to invoke digital content into their shows. It extends branding past the on-air episode, and it gives blog nerds, like me, something about which to write.

Character blogs, for example, really got going with NBC's "The Office," although I bet it was done even before Dwight Schrute started his. For HIMYM, Barney Stinson (one of the best characters created this decade, perhaps second ONLY to the aforementioned Schrute) has a blog on how to be awesome.

It includes an application to be his wingman. Long story short, Ted is no longer Barney's wingman ... but last week SNL's Will Forte gave it his best shot.

What's not shown in this video is what causes Forte's character to get nosebleeds. Seriously, I collapsed in laughter.

However, and this would be "second," lilyandmarshallselltheirstuff.com as a means to do good was really a hell of an idea. Just a good karma thing to do.

They apparently didn't plan on it doing so well though because as of midnight, it's down. Bombarded with traffic. One of the first rules of the dot-com era as it pertains to building a Web site for the purpose of eCommerce is and has always been: Prepare for success.

Actually, I'm pretty sure that's somewhere in the Bro Code.
