My teacher told a story about a ghost who failed math. I said, 'Did the ghost get a D?' She said, 'He haunted the teacher.'

My neighbor said he was a ninja who fought a dragon. I said, 'Did you win?' He said, 'I got a coupon for free pizza.'

My brother said he talked to a talking parrot who had a PhD. I said, 'Did the parrot write a book?' He said, 'He wrote a whole library.'
