The show called 'Hollywood Hen Pit' starring Doug Melnyk and Ian Mozdzen, who have been known for their edgy performances, having raised eyebrows in 2011 with their Fringe play 'Monopoly Man Pit.'
This year's performance is about the life of an aging Hollywood starlet as performed by two nude men.
"What I saw were not one, not two, but three mayonnaise enemas," said Fringe Festival reviewer Michelle Palansky, who was in the audience Friday night.
"By the third time…I was like, you know, this is gratuitous. I do not need to see any more mayonnaise enemas for the rest of my lifetime."
The show, that is completely improvised, to the surprise of many also featured oral sex between the two men.
"Fellatio was performed," said Palansky. "Not for very long, for a couple of seconds, but definitely performed," she said.
Palansky explains that the sexual act was not planned, it just happened, adding that even the stage technician was surprised.
"That was just in the heat of the moment in the middle of the show," she said. "It was sort of a non-climax. Literally and figuratively."
The Winnipeg police said performing sexual acts on stage are illegal, and Palansky said the actors should have known better.
"You can't be a performer on stage in Winnipeg, or any other city, and not know the laws of the land," said Palansky. "And as far as I know, everyone should know that live sex acts are not allowed on stage period."
In order for the police to investigate, a formal complaint would have to be filed, non of which had come in Saturday.
CBC News has contacted the Fringe Festival, but calls have not been returned.
The show is set to take the stage again Sunday at noon.
