John Bercow's decision to dub Her Majesty the "Kaleidoscope Queen" as he introduced her to Parliament on Monday appeared to draw the scorn of the prime minister.
Delivering a speech in Westminster Hall, the Speaker the assembled audience of MPs and peers that Britain had become "bigger, brigher and better" during the Queen's 60 years on the throne.
While the Speaker's wife, Sally, smiled on as her husband spoke. Bercow's choice of language drew a different reaction from a seemingly unimpressed David Cameron, who was captured on TV shooting the Speaker a lengthy dirty look.
If prime ministerial looks could kill, there would have quickly been a Speaker shaped hole in the back of Westminster Hall.
