– Miss, when was the last apocalypse?

– Apocalypse? There hasn’t been one!

– Don’t they happen all the time?

– Er, no.

– But wasn’t there an apocalypse just a week or so ago?

– What do you mean by apocalypse?

– You know when the moon goes in front of the sun?

– That’s an eclipse

– Oh right. And what’s an apocalypse again?

– The End of the World!

– Oh right. (Turns to friend) There’s not likely to be an apocalypse next week after all then.
