You know you’re in for a night of laughs when the setting for a show is a classroom and the smooth tunes of Salt ‘N’ Pepa’s Let’s Talk About Sex opens the show. Enter the charming Mark Butler and you’ll be wishing you really were back at school in a class on human reproduction with him standing at the blackboard.

Taking on the role of an incompetent Catholic school teacher, Butler cheekily navigates his way through what many would consider to be an embarrassing and dangerous topic: sex. And not just sex for procreation, sex for recreation as well. After explaining the basics of the male and female genitalia and assuring the class that everybody is different, he then reveals that babies don’t come from storks or God (just fat ladies’ stomachs), and moves on to the most important aspect apparently, of how babies are made. And so begins a lesson on topics that range from fellatio and masturbation to sex positions and fetishes. Using hilarious analogies like purse for punani (vagina) and pen for penis, Butler seduces the audience into participating in the class, asking volunteers to help by playing games such as pin the clitoris on the vagina and getting someone to demonstrate how they would put a condom on a banana.

The topic of sex is a rich playground for comedians, and while Butler boldly treads the fine line of crudeness he never crosses it, making this show an absolute treat for those who love a bit of naughty humour. You’ll blush and laugh your way through the entire show but who knows, maybe you’ll leave having actually learned something new.
