Timed to the March Madness of the NCAA basketball tournament, CBS plans a new 10-episode scripted Web series called "Heckle-U" starring stand-up comedian Owen Benjamin and Tom Arnold. Benjamin plays a slacker kid who, with the help of his bartender uncle (Arnold), becomes a star heckler at college hoops games. So if you see a 30-second clip promoting this on your TV in the coming month or two, but cannot seem to find it on your TV, this is why. It debuts online in February. (THR)
