The 1937 movie 'Heidi' was a worldwide success and she became a famous and well-paid Hollywood star.

However, when she grew up she did not have the same success in the cinema industry. 

She later joined the US diplomatic service .

She served many countries as an ambassador and one of them was Czech Republic.

Her full name was Shirley Temple Black (STB)

                                  But...

StB was the secret police force in communist Czechoslovakia from 1945 until 1990.

So one day Shirley had to leave her office in US embassy in Prague. She left a big yellow post-it in which she had written in capital black letters:

                          I'LL BE BACK SOON.

                                       StB

Everybody panicked because they thought that the old StB not only had returned but had entered the US Embassy. Even Pentagon in Washington was informed. 

Shirley returned from toilet and solved the mystery...
