Mr. Prongs agrees with Mr. Moony, and would like to add that Professor Snape is an ugly git.

Mr. Padfoot would like to register his astonishment that an idiot like that ever became a professor.

"Albus Severus," Harry said quietly, so that nobody but Ginny could hear, and she was tactful enough to pretend to be waving to Rose, who was now on the train, "you were named for two headmasters of Hogwarts. One of them was a Slytherin and he was probably the bravest man I ever knew."

"There was a clatter as the basilisk fangs cascaded out of Hermione's arms. Running at Ron, she flung them around his neck and kissed him full on the mouth. Ron threw away the fangs and broomstick he was holding and responded with such enthusiasm that he lifted Hermione off her feet.
"Is this the moment?" Harry asked weakly, and when nothing happened except that Ron and Hermione gripped each other still more firmly and swayed on the spot, he raised his voice. "OI! There's a war going on here!"
Ron and Hermione broke apart, their arms still around each other.
"I know, mate," said Ron, who looked as though he had recently been hit on the back of the head with a Bludger, "so it's now or never, isn't it?"
"Never mind that, what about the Horcrux?" Harry shouted. "D'you think you could just --- just hold it in, until we've got the diadem?"
"Yeah --- right --- sorry ---" said Ron, and he and Hermione set about gathering up fangs, both pink in the face."

"Ah" said Dumbledore gently, "Yes I thought we might hit that little snag!"
"Snag?" said Fudge, his voice still vibrating with joy. "I see no snag, Dumbledore!"
"Well," said Dumbledore apologetically, "I'm afraid I do."
"Oh, really?"
"Well it's just that you seem to be labouring under the delusion that I am going to -- come quietly. I am afraid I am not going to come quietly at all, Cornelius. I have absolutely no intention of being sent to Azkaban. I could break out, of course -- but what a waste of time, and frankly, I can think of a whole host of things I would rather be doing."
— J.K. Rowling (Harry Potter and the Order of the Phoenix)

"He can run faster than Severus Snape confronted with shampoo."
— J.K. Rowling (Harry Potter and the Deathly Hallows)

"You could say sorry," suggested Harry bluntly.

"What did you have to imitate her for?"
"She laughed at my mustache!"

"Well?" Ron said finally, looking up at Harry. "How was it?"
Harry considered it for a moment. "Wet," he said truthfully.
Ron made a noise that might have indicated jubilation or disgust, it was hard to tell.
"Because she was crying," Harry continued heavily.
"Oh," said Ron, his smile faded slightly. "Are you that bad at kissing?"
"Dunno," said Harry, who hadn't considered this, and immediately felt rather worried. "Maybe I am.""

"You'd think people had better things to gossip about," said Ginny as she sat on the common room floor, leaning against Harry’s legs and reading the Daily Prophet. "Three Dementor attacks in a week, and all Romilda Vane does is ask me if it’s true you’ve got a Hippogriff tattooed across your chest."
Ron and Hermione both roared with laughter. Harry ignored them.
"What did you tell her?"
"I told her it's a Hungarian Horntail," said Ginny, turning a page of the newspaper idly. "Much more macho."
"Thanks," said Harry, grinning. "And what did you tell her Ron’s got?"
"A Pygmy Puff, but I didn’t say where."
— J.K. Rowling (Harry Potter and the Half-Blood Prince)

"Yeah, someone might slip dragon dung in it again, eh, Perce?" said Fred.

"That was a sample of fertilizer from Norway!" said Percy, going very red in the face. "It was nothing personal!"

"It was," Fred whispered to Harry as they got up from the table. "We sent it."
— J.K. Rowling (Harry Potter and the Goblet of Fire)
