Two tidbits that I came across in an old file of miscellaneous linguistic stuff today, while I was looking for something else:
1. Sigismund (1361-1437), Emperor of the Holy Roman Empire, gave this answer to a prelate who, at the Council of Constance in 1414, had objected to His Majesty's grammar:
"Ego sum rex romanus, et supra grammaticam."
2. A Croatian dialect saying (rendered in very rough English-based spelling, without the Croatian diacritics, some of which are hard to render on line):
Kuliko jezikou chlovig zna,
Taliko chlovig valja.
Which translates to:
However many languages a person knows,
That's how much that person is worth.
