The Week of Fun saves the best for last. Laff Hole, the weekly showcase put on by the People's Republic of Komedy, is arguably the best comedy show in town. Along with the regular cast of crazies, this week's show features the amazing Randy Liedke, a surreal mountain man with a heart of gold, who will be filming a DVD. (Chop Suey, 1325 E Madison St, 324-8000. 9 pm, $5, 21+.)
