It's all Roman to me

The BBC reported (Sept. 19, 2014):

India's state TV channel has fired a news anchor for referring to Chinese President Xi Jinping as "Eleven" Jinping.

The presenter apparently confused Mr Xi's name with the Roman numerals XI.

Of course, there's also "it's all Arabic to me": "The young teacher introduced [a World War II veteran] by saying that the speaker was a veteran of World War Eleven." But that might well be apocryphal, and apparently the Red Skelton Show used a similar joke in the mid-1960s (as did Joan Rivers in 1984).

Thanks to Judge Andrew Guilford; I saw these items in a very interesting draft article of his on headings in briefs.
