"Come, don't be depressed!" cried the Rydrake. "Let Zygons be bygones, and all that. I shall find something to cheer you up."
He finished his ice and did a quick circuit of the bar, searching for anything that might restore the Doctor's former good mood; however, he was forced to acknowledge that there was nothing of interest in it, and also that he had no idea what might cheer the Doctor up. Stumped, he was about to give up when he spied a payphone, and hit upon what he thought was a brilliant idea.
The Rydrake took a few coins from the barman's pocket, put them in and dialled the number for Rent-A-Clown.
"Good morning," he said. "I would like to rent a clown, please."
He listened.
"Very well," he agreed at length. "That would be perfect."
His good deed done, he sat down and waited for the clown to arrive.
