Draco: Hey Potter! This horrible potion smells as disgusting as you do
Harry: Sod off, Malfoy
Professor: Potter! Malfoy! Be quiet, both of you!
Harry: Yes professor
Draco: But it's true, that horrible thing smells just like the scarhead does!
Professor: Malfoy! Shut up!
Draco: Yes professor
Professor: Now, class. Can anyone tell me what this potion is? Yes, Miss Granger?
Hermione: Amortentia, sir
Professor: Good, very good. And what is exactly Amortentia? Yes Miss Granger?
Hermione: Amortentia is the world's strongest love potion, and it smells like what the particular person is attracted to. And yes, Malfoy, we all heard your comment.
