Drinking water has been cut off for 2 days... There was no prior notice just as when heating had been arbitrarily cut off. Two storey-ful of researchers were scrambling to boil water from bathrooms which fortunately still had water. Thus we regarded the problem solved and stayed.

Then we noticed that both arXiv and MathSciNet were cut off. Calamity has stricken. 😱

Pale ghostly figures streamed out of our towering building, muttered complaints to each other and gradually settled down onto lawns to have picnic...

There was an anecdote about Professor B. During one of the conference talks, the fire alarm rang. He went to the exit, shut the door to attenuate the volume of the shrieking alarm and then signalled the speaker to go on.
