"But what exactly is the use of a rubber duck?" Arthur Weasley, a muggle enthusiast, asked.
"It has no use, Arthur," replied Hermione Granger, a witch with muggle parents. "It's just for floating in the bath for fun."
"But... It must have a use," Ron, Arthur's son, exclaimed. "Why else would it exist?"
"She's right, it has no use," Harry Potter replied. "It's just a useless item."
"And besides, Google said it has no use and therefore it doesn't have a use," Hermione added.
"Who said Google was right?!" Arthur asked, "And, what is Google?"
"I'm not going to explain Google because that'll take us down a whole new road!" Hermione rolled her eyes. "Put it in the bath next time you have one. Then you'll see its use is to float."
"Are we seriously going to act on something she's Googled?!" Ron cried, sounding rather annoyed.
"Yes. Yes we are," Arthur replied, grinning. He grabbed the duck and ran off upstairs to test out whether the duck really did float.
