Bouncy

King Wilbert looked around his dilapidated castle and cursed his ancestors for wasting their maintenance budgets on parties and wars.
“C’mon, Mildred,” he said to his queen. “Let’s go shopping for a new castle.”
Architects drew up plans for a new castle, but the royal accounts could only afford a inflated bouncy castle.
“I’m not living in that thing!” said Mildred.
“Well, we could rent it out for kids birthdays until we can afford a real castle,” said Wilbert.
Which they did. And they dressed like clowns and made balloon animals and painted kids’ faces.
And lived happily ever after.
