Step aside Michael D., we have a new national treasure. Mary Lou McDonald may have just become our favourite politician ever after stepping up to An Taoiseach Enda Kenny, telling him off for grinning at her when she was asking a question and then calling him a dick under her breath when he or someone else interrupts her. It's not clear who the culprit was, but Mary Lou's frustration with the old boy's club that is the Dáil is.  Priceless.
