I was taken aback this morning by some standard legal boilerplate published on an Apple news site about a contest that Apple is running:

ELIGIBILITY: All entrants must be at least 18 years old and must be legal residents of the United States, including the District of Columbia. [emphasis added]

Typically, these sorts of legal clauses are only added when there’s been some sort of legal protest or confusion in the past, which implies that someone, somewhere, managed to think that people living in D.C. aren’t even legal residents of the United States, let alone citizens. That’s gotta take the cake.
