Kroll Show works often enough to make a name for itself among young males in particular. Men of a certain age might be more resistant, but still susceptible.
In almost every case, even the good concepts (like Kroll as a mic'ed up referee during an NBA game, needily badgering the players) peter out, while the more esoteric ones, such as a spoof of Canadian dramas, are a little too precious for their own good, eh?
