Over-Egging The Pudding

I really hadn't intended to say anything else about Paul Ryan's marathon time, but then I couldn't resist linking to this article on the BBC News website. It's always interesting to me to see how American politics is playing in other countries, but what really got to me this time was the oh-so-British expression in the 4th paragraph from the end. I'd never heard of "over-egging the pudding," meaning to exaggerate, but it's definitely in my head now. I can't wait to have a chance to use it in a sentence.
