This interestingly seems to parallel a comment by the current British Prime Minister David Cameron, when he first entered office.

"We're all going to have things thrown back at us. We're looking at the bigger picture. ... And if it means swallowing some humble pie, and if it means eating some of your words, I cannot think of a more excellent diet."

This was in response to a reporter who asked him why he was working with Nick Clegg, a man he had once described as a "joke". At the time I thought it was a spontaneous remark, but after seeing the above, it looks like he may have been quoting.
