A very odd day!

I was walking up to Sainsburys one day when I saw something very strange. I saw a elephant who was joyfully plodding along Muswell hill road ,casually, as if it was totally normal for elephants to walk across the streets. The elephant was not all on its own by the way, on its back was sitting a little plump man with jubilant rosy cheeks who was grinning wildly.
And then I noticed something that was even stranger. I saw another elephant, and then another. Then two more, three more, TEN more elephants toddling along the road with ten little men sitting happily on them.

What happened next gave me a great shock. What happened next is this: With an enormous surprise I realised that I was the only human on the street that was not riding on an elephant!
