-During a Potions lecture by Professor Slughorn-

Harry and Ron are being late

Professor Slughorn:"Ah Harry my boy beginning to worry for someone with us I see ..."

Ron:"Ron Weasley sir. I'm dead all full of potions a menace actually so I'm propitious."

Professor Slughorn:"Nonsense will taught you out of any vendor Harry's is a friend of mine. Get your books out."

Harry:"I'm sorry sir I have actually got my book yet. Ron was wrong."

Professor Slughorn:"Not to worry god, get one from the cupboard."

Harry and Ron are going over to the cupboard

Professor:"As I was saying I prepared some concoctions this morning .. Any ideas what these might be?"

Hermione raises her hand

Professor Slughorn:"Yes miss .."

Hermione:"Miss Granger sir.."

Hermione:"That one there is Veritaserum. It's a truth-tellimg serum."

Harry opens the cupboard and fights with Ron for a book cause one is brand new and the other one looks old

Hermione:"And that would be Poly juice Potion. It's terribly tricky to make. And this might be Amortentia. The most powerful love potion in the world. It's rumoured to smell differently to each person, according to what attracts them. For example, I smell.. freshly mown grass, new parchment .. and .. spearmint toothpaste"
