Even just touching the Queen has provoked debate in the past. In 1992, Australian Prime Minister Paul Keating was dubbed "The Lizard of Oz" when he touched the Queen's back during a royal tour; his successor John Howard was accused of a similar gesture in 2000, although he denied he actually made contact. This time, however, photographs and film clearly show that the Queen made the gesture first, putting her hand on Mrs Obama's back during an animated conversation in which the two woman discussed their significant height difference.
