My parents always said that bad politics creates the best comedy. There's a lot of comedy shows filmed in socialist Poland and they're amazing. Both really clever and funny. Even though they had to be reviewed by censors first, the things that got through were still very much about politics. Some so pointed, I still don't know if the censors were too lazy to read the script, or ignored the rules...
I always wonder if the subversive elements that make it through aren't "missed" necessarily by a censor. I like to think that it's an act of subversion, a protest-by-omission, by some of the few people of conscience deep in the belly of the beast.
