Say it ain't so! After seven seasons of gun battles, substance abuse and general mayhem, the Trailer Park Boys are signing off.

No more Ricky, Julian and Bubbles? No more ridiculous money-making schemes? No more drunk male prostitutes?

"There's not going to be any more seasons," John Dunsworth, who plays insane trailer park supervisor Jim Lahey on the Showcase original series, said in a recent interview.

"Never again."

Dunsworth and fellow actor Pat Roach, better known as the cheeseburger-obsessed and no-shirt-wearing Randy, are currently touring the country, performing songs and skits as their TPB characters.

The two actors spoke candidly in a telephone interview about the future and history of the TPB franchise.

The saga began in 1999 when Canadian writer/director Mike Clattenburg released a mockumentary movie about a couple of cocaine-snorting trailer-park buddies who kill unruly pets for money. The film, Trailer Park Boys, not to be confused with the 2006 TPB flick, featured many of the same actors who would be in the television show a few years later.

Roach, for example, who has known Clattenburg almost his whole life, was cast as a shirt-wearing, non-cheeseburger-eating character. The movie eventually turned into a television series in 2001 sans cocaine use and animal killing.

Another difference between the original movie and television show was Roach's character. He and Clattenburg were walking around on a hot summer day with their shirts off. This gave Clattenburg an idea.

"Mike said (my new character) should never wear a shirt," Roach explained.

From that, Randy was born. Ever since, the beer-bellied eccentric is almost never seen wearing one even in the winter. And no real explanation is given for the bizarre behaviour, other than "I don't wear shirts."

Although fans quickly took a liking to Randy and the Trailer Park Boys series, Roach had a little explaining to do. While acting on the show, he also worked as a sales executive for Sparkling Springs, a bottled water company.

"I was popular with everyone except my boss," said Roach, who holds a business degree from St. Mary's University in Halifax. "He was shocked that I was on TV running around in my underwear."

When the character fights, Randy sometimes removes his snug pants for better mobility and balance, leaving just his tighty-whiteys on for the visual protection of others.

Randy also has the distinction of being a former and, when times are tough, current male prostitute. In fact, the character is so outrageous that Roach's nine-year-old daughter and seven-year-old son are not allowed to watch Trailer Park Boys.

"It's kind of hard to explain you're a male prostitute," he laughed.

With perhaps the most famous gut in Canada, Roach has a method for making sure it maintains its round, protruding form.

"I'm on a seafood diet. When I see food, I eat it," he joked.

And even though millions of people have seen it already, Roach remains a little shy when he bares his chest for all to see.

"I still get embarrassed, but I'm used to showing it by now," he said.

While the end of the series may break the hearts of fans, there are reasons to celebrate, maybe even slam back a couple drinks.

A new, one-hour television special will air next month. Say Goodnight to the Bad Guys -- A Trailer Park Boys Special will be broadcast Dec. 7 on Showcase.

Another movie, filmed last summer, is also on the horizon. Trailer Park Boys -- Countdown to Liquor Day hits theatres in fall of 2009, Showcase.ca reports.
