Been here before

Aye, well.  The Zoo is crying wolf again:

Following a sustained frenzy of pregnancy speculation on a scale that perhaps only the Duchess of Cambridge can relate to, Scotland's celebrated female giant panda, Tian Tian, is likely to give birth at the end of this month, Edinburgh zoo has announced.

The 10-year-old panda underwent artificial insemination in April after she and her male counterpart loaned to the zoo from China, Yang Guang, stubbornly declined to proceed as nature intended.

I hope that it is not too ungallant to suggest that the Countess of Strathearn (to give her Scottish title) is rather more reliable when it comes to moherhood.
