An Australian radio host was yanked off-air Wednesday for joking about weight- loss at concentration camps, less than a month after serving a suspension for quizzing a teenage rape victim. Sydney's 2Day FM said shock jock Kyle Sandiland's remarks that the best way for comedy actress Magda Szubanski to lose weight was to go to a concentration camp were 'unacceptable'. Sandilands said Szubanski, the public face for a chain of weight loss clinics whose father fought in the Polish resistance during World War II, had not slimmed down enough. 'You put her in a concentration camp and you watch the weight fall, like she could be skinny,' he told listeners Tuesday. He later apologised. Szubanski, best known for her role in the 'Kath and Kim' comedy series, condemned the remarks. 'I couldn't give two hoots about what Kyle says about me, but to trivialise what happened to people in concentration camps is abhorrent,' she said. Sandilands returned to the airways three weeks ago after being suspended over a stunt in late July where a teenage girl hooked up to a lie detector revealed she was raped. The disc jockey was sacked from his role as a judge on the television talent show 'Australian Idol' over that incident. 2Day FM has not said when or if he will return to the airwaves.
