Doctor Who and the Laughing Bridge

A sculpture park visit would not be complete
Without three giant men with holes in their feet.
And writing a word in the dust on a sign
'Alone' was the word, but still he felt fine.
He continued his picnic, all by himself,
A crushingly lonely but well-fed elf.
At the lakeside he thought about ending it all
His lonely picnic had been too great a fall
From the dizzying heights of society life
He fell into trouble and fell into strife.
It was sad for Matt Smith, who had been a good friend
So he went back in time to that time last weekend
When they'd all had french fries with lashings of sauce
And hundreds and thousands, and gravy (of course).
When they had finished, they were all promptly sick
But two dozen aspirin soon did the trick
In twenty-five minutes they were back on their feet
And they went off to Greggs for a well-deserved treat.
