The last Rigoletto that I saw took place in the Oval Office.
(Oh, and when I went to see The Merchant of Venice last year at Stratford-upon-Avon, the opening scene was set in .... Las Vegas!, and, actually, the whole thing got darker and darker as the play went on (as it should). Patrick Stewart was great as Shylock, and there was one laugh-out-loud moment: Lorenzo and Jessica were at a masks-and-disguises party before setting off to Belmont. He was dressed as Batman and when Jessica said that she was going to be disguised as a boy, she threw off her cloak and revealed that she was Robin. A bit vulgar but funny.)
