Unfortunately not from The Onion:
Baroness Gardener said: "I speak as a member of the All-Party Group on Obesity. Why is it that in central London you can hardly find a thinly sliced or medium-sliced load of bread to buy, and any sandwich you buy in any supermarket is now made with thick bread?
"While the House of Lords continues to use medium-sliced bread - and very nice bread - in its sandwiches, even the House of Commons has moved to thick bread.
"Surely at a time when we want to reduce people's consumption, there should be more pressure from the Food Standards Agency, or one of the many departments the Minister speaks about, to take us back to normal-sized bread instead of these super-sized sandwiches."
