“Mr. Moony presents his compliments to Professor Snape, and begs him to keep his abnormally large nose out of other people's business.
Mr. Prongs agrees with Mr. Moony, and would like to add that Professor Snape is an ugly git.

Mr. Wormtail bids Professor Snape good day, and advises him to wash his hair, the slimeball.”

"I am very touched, Harry.”
