TORONTO - The Trailer Park Boys are going to get high again.

Mike Smith, Robb Wells and J.P. Tremblay of "Trailer Park Boys" have been cast to play multiple characters in a new Showcase series called "The Drunk and on Drugs Happy Funtime Hour."

The series will centre on the cast of a fictional children's show, played by Smith, Wells and Tremblay, who accidentally ingest an addictive hallucinogen mixed by a character played by Rush guitarist Alex Lifeson.

As the series unfolds, the characters will contend with the bizarre cast of hallucinating children's show characters, a dysfunctional crime family that runs the town and a dangerous cult.

Showcase has greenlit the series for six episodes that will air in 2010.

"Trailer Park Boys" ended its seven-season run in 2007.

"The series is definitely a departure from our previous work, but with bold characters and a story line that pushes the envelope, 'Drunk and on Drugs' still has a huge dose of our trademark humour that I think our fans expect from us," Wells said in a release.
