Stupid policies and situations that make you want to deliver a tirade worthy of Last Week Tonight with John Oliver.
This subreddit was inspired by the sort of rants you'd see from John Oliver or Bill Maher, but other than that, isn't directly related to any television personalities or shows.
If you're more interested in things that were actually on late night talk shows, check out /r/LateNightTalkShows.
