The card from Buckingham Palace had two choices: "I can kneel" and "I cannot kneel." And for those who can kneel but not get up again? After being made Britain's newest knight last week, Peter Ustinov, 69, reported there's "a handy rail to assist knights of a certain age." Busy Ustinov has a new novel and a future TV series, and has been touring the world with his one-man show.

Alas, "when she opened her mouth to say something else," says Sir Peter, "it was the next gentleman's turn."
