Brain Damaged

"I do fear for her sanity," said the First.

"I suspect brain damage," said the Second.

"It must have been the fall," said the Third. "I witnessed it. She was stalking me, you know."

"You don't say?" said the Fourth. "Just what you'd expect."

"And that's not all," continued the Third. "Afterwards, she pretended to be my maid servant and stole from my house! How did you all come to know her?"

"Tsk, tsk," said the Fourth. "She asked me for directions, but couldn't tell me where she was going."

"She couldn't even tell me who she was!" snorted the Second, drawing himself up to his full inconsiderable height.

"Ah," said the Fourth. "She rudely crashed my party and couldn't even tell me how a raven is like a writing desk!"

"As to that," said the First, fading quickly, "nor could I."

"Harrumph," said the Second, puffing avidly on his hookah. "So what's the answer?"

"Heck if I know," said the Fourth. "That's why I asked. But the point is, the point is ... she didn't know! Obvious brain damage."

"I haven't got time for this!" squeaked the Third, nervously tugging at his pocket watch. And he scampered off for his next appointment.

"You can always spot the brain damaged," puffed the Second. "Very unstable people."

"What time have you got?" asked the Fourth. "Still 6 pm?"
