One afternoon in the Artic, a father polar bear and his son polar bear were sitting in the snow. The son polar bear turned to his father and asked, "Dad, am I 100% polar bear?"

The father polar bear replied, "Of course, son, you're 100% polar bear."

A few minutes pass, and the son polar bear turns to his father again and says, "Dad, tell me the truth. I can take it. Am I 100% polar bear? No brown bear or panda bear or grizzly bear?"

The father polar bear replies, "Son, I'm 100% polar bear, your mother is 100% polar bear, so you are definitely 100% polar bear."

A few more minutes pass, and the son polar bear AGAIN turns to his father and says, "Dad, don't think your sparing my feelings if it's not true. I gotta know -- am I 100% polar bear?"

The father polar bear was distressed by this continued questioning and asked his son, "Why do you keep asking if you're 100% polar bear?"

"Because I'm freezing!"

The Examination

An attractive young girl, chaperoned by an ugly old crone, entered the doctor's office. "We have come for an examination" said the young girl.

"Alright," said the doctor. "Go behind that curtain and take your clothes off."

"No, not me" said the girl. "it's my old aunt here."

"Very well," said the doctor. "Madam, stick out your tongue."
