Did anybody else happen to catch the mockcommercials on NBC tonight featuring the cast of “The Office”? I nearly missed them while speeding through the other stupid ads (i heart TiVo), but was lucky enough to see them all; there was even one that aired during “My Name Is Earl.” Originality: this is exactly why the series is doing as well as it is. NBC has definitely got something here. Maybe next week we’ll see the cast of “Scrubs” doing fake PSA’s of their own. We can only hope.
