Severus Snape gasped as he hit the floor of the cell hard enough to have the wind knocked out of him. Shivering as he pushed himself back up into a sitting position, he managed to sneer weakly at his jailers, who countered with much more confident smirks. "Don't bother locking the door; Dumbledore is no doubt already working to free me."
"Oh, he's trying, we'll give him that much, but seeing as how everybody else in power is working to keep you here, I recommend you get comfortable. In fact, we put you in the cell next to an old buddy of yours, just to make sure you don't get lonely during your stay." The Auror slammed the door shut and strolled off, whistling merrily. "Have fun you two!"
Snarling, Snape took a moment (and several deep breaths) to calm himself before moving to the bars of his cell. "Who's there?"
First there was silence, then shuffling, before a rasping voice answered from the neighboring room. "Who's asking?"
"Severus Snape. Do you remember me?"
"...Snivellus. How could I ever forget you?"
"NO!"
"YES!"
"NO!"
"YES! ...hey, wanna hear a couple of hundred knock-knock jokes I made up?"
"NNNNNNNNOOOOOOOOOOOOOOOOOOOOOO!!"
