The doorbell tinkled as a certain redhead made her way into the shop.

Ginny Weasley's eyes scanned over the shelves of jokes and tricks until a certain blue vial caught her attention.

"Hmm... Maximum Masculinity. I wonder what this does..." She proceeded to plop herself onto the shop's tile floor, in what her mum would call "a very unladylike manner," and read the vial's directions.

George, having heard the door's tinkling announcement, burst in from the backroom singing, "Welcome to Weasley's Wizard Wheezes, where our job is to..." He faltered when he noticed that his customer was only his little sister, "Oh. It's just you Ginny."

"Mmhm..." she nodded absently and beckoned her brother over. "Hey George, would this stuff work on a girl?"

"Maximum Masculinity? Nah. That stuff's for guys who haven't exactly hit puberty yet and still have squeaky voices. What, you want to enhance your manliness?"

Ginny looked up at him and grinned, "Shush, I was merely thinking about how it would feel to be a boy."

At that moment, Fred hustled into the shop. He went over to his sister and glanced at the vial she was holding, "What's this? Our ickle sister wants to be a boy?"

"Eh, I just wanted to try for a year, but George said this stuff only works on guys." She picked herself up from the floor and got ready to leave.

Fred and George looked at each other and shared identical grins, before calling out, "Wait," to their sister.

"We've got something for you-"

"-that we think you might find interesting."

George scrambled into the backroom and came back out holding a purple vial, labeled Girly Boy and held it out for Ginny to see.

"This hasn't gone onto the market yet because we haven't been able to test it."

"Or rather, we can't test it," Fred gestured to his body.

"We did test Boyish Girl, and it worked perfectly," George added in brightly.

"Except that George got caught and -"

"Shut up. Remember that time when -"

"You mean how -"

Ginny cleared her throat, "Back to the point?"

"Ahem. Anyway, we were thinking that maybe you would want to test it out for us?" George smiled hopefully.

"We'll pay you twenty-five galleons," Fred nudged her playfully.

Twenty-five galleons and she got to be a boy? This worked out for Ginny rather well, in her opinion.

She looked at her twin brothers, brown eyes lit up with mischief, "Fine. Tell me how this works."
