Parents need to know that this wedding-themed reality show is all about things going wrong at a very important moment -- and a lot of what goes wrong has to do with people behaving inappropriately. Nothing gets too edgy or graphic (expect more cake smashing than painful injuries, for example), but you're still laughing at other people's big day gone awry. Some parents might be concerned that the "stunt" weddings reflect a lack of seriousness about marriage (though others might feel that they put the whole "three-ring circus" aspect of weddings into perspective...).
Positive messages:Much of the show's fun/humor revolves around people behaving inappropriately -- but generally not extremely so. There's a fair amount of cake smashing and the like, for example. Some mild reinforcement of gender stereotypes.
Violence:Pratfalls aplenty. In an episode featuring a Klingon wedding, there's some fake Klingon-style violence, including a faux beheading.
Language:Words like "pissed" are audible and printed in subtitles. In one sequence, a bride thinks her groom said "vagina," when he said "Regina" (pronounced the same way), and then she makes a couple of jokes about it.
