Only Some were Under 18
By This is probably the best NYT correction ever:
Correction: An earlier version of this article misstated the number of girls younger than 18 who were allegedly invited to a villa by Prime Minister Silvio Berlusconi of Italy. Mr. Berlusconi is alleged to have invited about 40 women to the villa, but only some of them were allegedly younger than 18 at the time, not all of them.
