Tonks grinned sheepishly, "Sorry to move away from the ah, interesting, topic, but I really don't want to know. Unfortunately, I've never snuck out to Hogsmeade."
"Aw, Tonks! You're lame!" Fred gave her a disappointed look, as more than two thirds of the table drank.
"Despite what Hermione thinks," said George, "I've never intentionally given first-years untested Weasley Wizarding Wheezes."
"George!" exclaimed Fred as he drank, "That was just cruel. After all, you took the second-years!"
McGonagall gave Fred and George a frosty glare, "We will be having words about this later. As it is my turn now… " she trailed off, a smile on her face that could only be described as vicious, and waited for Albus to get very very worried. "I've never impersonated a Hufflepuff priest with multiple personality disorder at a session of the Wizengamot."
Albus' eyes twinkled even brighter, "Ah, Minerva, you've got me there. You'd be surprised at how many people weren't very amused. That was one of my finest moments..." He gazed fondly into space, as if remembering a joyous occasion, oblivious to the laughs all around the table.
Then Hagrid drank. All laughter stopped, and all eyes turned to him in shock.
"Hagrid? You have also experienced the wonderful sensation of being stared at by the wizarding community's most influential citizens as you argue with yourself and prance around the room in the clothing of the Pope?" asked Dumbledore delightedly, the only one not speechless. Hagrid blushed,
"Well, you told me how much you enjoyed it when you did it, so I figured I'd give it a shot, and it was mighty fun…"
Neville was the first to recover from his shock. "Moving on," he said, "I've never failed Charms, Transfiguration and Defense Against the Dark Arts all in one year." Snape gave him a look that could kill, and Neville wished he hadn't spoken. But the spell had already taken control, and Snape's hand unwillingly moved his glass closer to his mouth.
"Hah!" shouted Sirius, "I knew it!" Snape glared at Sirius darkly.
The door to the Room of Requirement opened. "My Inner Eye told me that a party was going on, and someone obviously misplaced my invitation," a misty voice broke in. Trelawney came in and sat down in a seat that appeared next to Dumbledore.
"Well at least I've never failed Potions," Snape shot back at Sirius weakly, his snarkiness obviously impaired by his alcohol intake.
"Me neither," said Sirius triumphantly.
"You're out of turn!" said Hermione.
"Ah, you got me!" said Trelawney, "and on my first round too!" She took a small sip first, and then a large swallow, "Oh, this brandy is good!"
Ginny looked put out. "It's my turn now." She thought for a while, ignoring the conversation that Bill and Harry were having about the pros and cons of goblin sex. "I've got it! I've never done it with a tree!"
Remus raised his glass "Cheers, Willow!"
Sprout looked at him askance. "Willow cheated on me?"
"What?" asked everyone else in the room.
"The Whomping Willow," explained Remus, "Don't worry, Pomona, it was a long time ago. I'm sure she's faithful to you now."
