What we're watching: Tonight Fox follows up American Idol with the premiere of a show that answers the question we have been dying to know: Are You Smarter Than a 5th Grader?, and according to Fox's listings we will hear that resounding no in Dolby Digital accompanying a 720p broadcast of our utter failure to grasp concepts taught in elementary school. ESPN2-HD also brings us a high definition preview of the upcoming Arena Football season, if you must have football now that the NFL season is done.

Our traditional high-def listings continue below.
