I think it was The Day Today,
it was a counciller (or MP) talking to a reporter about a demonstration to highlight old people being alone/homeless/cold or something at Christmas, it went something like:

"The old people will sleep in boxes outside the town hall on Christmas Eve. Then, we will set fire to the boxes to symbolise the plight of the elderly. Some people may still be in their boxes."

"You're going to burn old people at Christmas?"

"I'm not saying we're going to burn old people. What I'm saying is, old people may... burn."
