It is a bad idea to tell Professor Snape he takes himself too seriously...
"There will be no foolish wand-waving in here. I can teach you how to bottle fame, brew glory, even stopper death - that is if you turn out not to be the biggest bunch of dunderheads I've ever had the misfortune to teach. Yes, Mr Weasley?"
"So is this really magic?"
"Of course it is real magic, I don't expect you to understand the beauty of the softly simmering cauldron with it's shimmering fumes."
"Nice alliteration there Professor, it's a shame you couldn't think of another word for fumes..."
"Smoke, steam..."
"Thank you Mr Weasley and Mr Weasley for that unnecessary interruption. Now can someone tell me what you'd get if I added powdered root of asphodel to an infusion of wormwood? Yes... Mr Weasley."
"An infusion of wormwood with powdered root of asphodel in it Sir."
"That is incorrect, you would get an extremely powerful sleeping poti..."
"Technically though Sir, it is correct."
"No, it's not! 5 points from Gryffindor for contradicting me."
"Lighten up Sir, you take yourself way too seriously."
"Detention! Both of you, tomorrow night with me."
"Could we use that sleeping potion as an excuse not to go."
"NO!"
