A young woman decided to redecorate her bedroom. She wasn't sure how many rolls of wallpaper she would need, but she knew that her friend next door had recently done the same job and the two rooms were identical in size.
"Buffy," she said, "how many rolls of wallpaper did you buy for your bedroom?"
"Ten," said Buffy.
So the girl bought the ten rolls of paper and did the job, but she had two rolls leftover.
"Buffy," she said, "I bought ten rolls of wallpaper for the bedroom, but I've got two leftover?"
"Yeah?" said Buffy, "That's funny, so did I!"
Two old men were arguing the merits of their doctors. The first one said, "I don't trust your fancy doctor. He treated old Jake Waxman for a kidney ailment for nearly a year, and then Jake died of a liver ailment."
"So what makes you think your doctor is any better?" asked his friend.
"Because when my doctor treats you for a kidney ailment, you can be sure you'll die of a kidney ailment."
