Brown's Porridge

I just came across this quote.
“Tony Blair was like champagne and caviar; Brown is more like porridge,” Meghnad Desai, a prominent Labour member of the House of Lords and emeritus professor at the London School of Economics, told the BBC in April
Brown is more like cold porridge - and he wants to force it on to all of us.
I can't remember where it came from but there was an old miser in real life who never ate anything but cold porridge, and kept it in his desk drawer.
The idea was that if anyone came into the room he could slam the drawer shut and not have to offer to share it.
