Gryffindor Courage does not come in bottles labeled 'FireWhiskey'
Charming the label does not change anything.
Harry smirked as he looked at the new first years. It was two weeks into the semester, and they were already starting to crack under the pressure. He knew that he probably shouldn't do what he was about to, but it seemed like a hell of a lot of fun.
"OI! Mathews, come here a minute."
The first year boy squeaked. Being addressed by Harry Potter, was apparently something to squeak over.
"Yes, uhm, Mr. Potter?"
"I want you to do me a favor?"
"Ok!" Said the over enthusiastic Gryffindor.
"I've got this bottle, a small bottle, of Gryffindor Courage, and I need you to drink it for me?"
"Yeah!" Mathews said, "Sure, anything for you Harry."
The Older Gryffindor smiled charmingly, and handed the eleven year old the bottle.
"You have to drink it right now," Harry said, trying to keep a smirk from forming on his face.
Mathews unscrewed the cap and sniffed it, before shrugging and tipping it back.
Before he could though, they both heard, "HARRY JAMES POTTER! What do you think you're doing!"
"Awww 'Mione!"
"No, don't you dare 'Mione' me Harry. Do you realize how much trouble you're in?"
Harry had the gall to look sheepish. "Well, it's not what you think...it's Gryffindor Courage."
"No Harry, it's Firewhiskey, and charming the label doesn't change anything."
