On Monday morning, the world learned of the death of Margaret Thatcher, the first female British prime minister. A champion of free-market economics, she was arguably the country's most important political figure since Winston Churchill. She died following a stroke at the age of 87.

One of the first hashtags to spring up on Twitter on Monday was #nowthatchersdead, created by a website critical of Thatcher.

This spurred confusion among Cher fans, mostly Americans, who read it as "Now that Cher's dead." Soon other Twitter users, including comedian Ricky Gervais, started mocking these panicked fans. Here's a look at some of the tweets about the confusion.
