Three Sheets is the first television show to be produced as a drinking game. When Zane drinks, you drink. First person to see the monkey makes someone else finish their drink. And when Zane talks about his friend, Steve McKenna, it's a social (everyone drinks).
The monkey, Pleepleus (plee-plee-us), seen in every episode, was a gift from Zane's wife. She packed it in his suitcase on his first episode (Galway, Ireland). He puts it in every show to tell her he loves her.
In the Czech Republic, Zane left Pleepleus (the monkey) in the beer bath. The Chodovar brewery FedExed it to Zane in Venice, where he opens the box during the show. That is why, in Croatia, the monkey only appears as a photo.
In Jamaica, the hangover cure was a 'special tea'. The main ingredient of the tea was marijuana. After the segment, Zane was unable to shoot for the rest of the day. But he was reportedly very happy.
The drinking game was introduced in the Costa Rica episode.
