Currently, an interesting anecdote is making the rounds among the students at Hogwarts.
That Ravenclaw student who spent a small fortune on Baruffio's Brain Elixir was invited by Snape to afternoon tea. The Potions professor claimed that most of the Baruffio's Brain Elixir brewed by wizards contained deadly poison, and under the pretext that drinking poisoned Baruffio's Brain Elixir could turn someone into an idiot, he demanded that the student hand over the potion for inspection.
The Ravenclaw student claimed that the potion came from Mr. Dagworth, making it safe and reliable, and added that he had already drunk the Baruffio's Brain Elixir without turning into an idiot.
