This week's provincial budget has led to some rough and tumble language from Alberta's politicians.

Politicians of all colours have used blue language to describe a budget full of red ink.

Liberal leader David Swann described the Alberta government's budget as "simply covering their asses."

Finance Minister Ted Morton later told reporters "nobody has any interest in having a public pissing match with the City of Calgary or any other city" over cuts to infrastructure funding.

Ald. Joe Connelly responded: "I would tell you right now it's not a pissing match, but we want some answers," he said.

A history of foul language

Bad language is nothing new for Canadian politicians, said Mount Royal University political science professor Keith Brownsey.

"I would argue that things are much calmer today than they have been. Blue language, threats, all sorts of insults were thrown back in the day," he said.

"Even in the 1890s debates were pretty hot and heated and sometimes inappropriate language was used. Various members of parliament accused each other of all sorts of heinous offences and there were the occasional threats of violence."

Foul language isn't new to Alberta of course. Remember this gem from then-Premier Ralph Klein during the province's first outbreak of mad cow disease?

"I mean this thing is so damn stupid. I can't tell you how stupid it is," Klein said.

Teachers not impressed

Ann Marsh, who teaches etiquette in Calgary, said profane language shows a lack of professionalism. Frustration can eventually lead to regression, she said.

"Sometimes we do we regress and we are back on the playground. Not necessarily that it happens on the playground," she said.

Teachers attending a convention in Calgary on Thursday weren't impressed with Morton's, Connelly's and Swann's comments.

"We don't use that kind of language in the classroom and I don't appreciate professional people speaking that way," Susan Sowka said.

Added teacher Andy Maksymetz: "It's a bad influence and it teaches kids that it is acceptable in public places."

Brownsey said despite a history of potty mouth politicians, voters don't always agree with bad language.

"I think today we expect more out of our politicians."
