1. HUMOUR
One afternoon in the Arctic, 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 got to 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!"
