A.V. Club reports Michael Cera and John Hawkes have been recruited to star in the How & Why pilot for FX. They also give us plot details!

Hawkes is set to play the lead role of Goodman Hesselman, host of the How & Why educational show-within-the-show, who loses his passion for explaining how complicated things work, yields his show-within-the-show to a younger host, then moves to a smaller town, where he tries to create a similar, yet significantly less popular, parallel-show-to-the-show-within-the-show.

According to Deadline, Hawkes’ character then also “encounters the supernatural world,” which is, indeed, its own show-surrounding-the-parallel-show-to-the-show-within-the-show. Cera will play Hawkes’ boss at his new studio. (Source)

Strange but true. Can't wait!
