Fred and George's business, Weasley's Wizard Wheezes was going extremely well. Their profits in the last year had been a third of the profits Zonko's Joke Shop had earned in their ten years of business.
"Well mate, who should do the honors?" asked Fred. "Do you wanna be Ron first and ruin his life, or should I?"
"I will," said George with a mischievous grin. He raised the bottle that had arrived in the post from Hermione and guzzled it down.
