First, there was Barney’s blog.

Now, “How I Met Your Mother” showcases its utter coolness by offering up a weeklong string of behind-the-scenes footage, hosted by a different member of the cast each day this week.

The clips all give us some insight into what goes into filming an episode of “How I Met Your Mother,” but, more specifically, the next episode. That means that you can follow the process for a week before being treated to the very episode on which the behind-the-scenes stuff hinges.

The first comes today from Josh Radnor, who plays lovelorn Ted. Radnor takes us to a table read and executive producer and co-creator Craig Thomas talks a little bit about the writing and filming process.
