A senior Tory MP launched an attack on the website of CBBC's Dick and Dom in da Bungalow in the Commons, asking whether it was in the public taste.
Mr Luff criticised the duo's humour and "embarrassing" games
Peter Luff, the Conservative MP for mid-Worcestershire, attacked site for depicting "grossly embarrassing personal situations".
He invited Culture Secretary Tessa Jowell to his office to watch the show.
She said it was the government's role to develop a BBC charter, but the BBC was responsible for taste and decency.
Mr Luff said: "You can join me in playing How Low Can You Bungalow, a test to see your response to grossly embarrassing personal situations, largely of a lavatorial nature.
"Pants Dancers in the Hall of Fame, photos of children with underwear on their heads, Make Dick Sick, a game which I think speaks for itself, and finally Bunged Up, in which you play a character in a sewerage system avoiding turtle's poos coming from various lavatories," he said.
"Is that really the stuff of public service broadcasting?" Mr Luff added.
The BBC defended the show, which is screened on BBC One on Saturday mornings and features presenters Dominic Wood and Richard McCourt, because it said it was aimed at a younger audience.
"It is pure fun and entertainment, aimed at 8-12 year olds, so it is unsurprising that it doesn't appeal to some adults.
"It gives children a chance to laugh and enjoy themselves at the start of the weekend and we have many letters and e-mails of appreciation for the show, from both children and their parents.
"We do take our role as a public service broadcaster very seriously: any criticisms are always looked into, but have to be addressed in the context of the target audience for the show and its remit to entertain young children," it said.
The show, which features games where adults and children have to shout the word "bogey" as loud as they can in public places, had already courted controversy.
Last year, Wood was criticised by media watchdog Ofcom for wearing a t-shirt with a sexual slogan on it.
