Well, here is a new take on the Amorentia potion. You and your friends know it is coming up. the class knows, heck the whole school knows. Everyone dreads it because Snape uses this chance to cruelly make fun of all the students.

Suddenly you have an idea, instead of saying what you actually smell from the potion, you intend to use this as an opportunity to embarrass Professor Snape. You and your friends spend the week before figuring out what scents you can name that wouldn't immediately give away that this was a prank, or make it too obvious it was Snape.

Instead of dreading the day, you and your friends are looking forward to it, wanting to see how the strict, stern, and cold Potion's Teacher's reaction would be.
