Young polar bear sitting on the ice talking to his dad.
"Dad, am I a polar bear?"
"Of course you are, son. You have white fur so you can blend in with the snow and catch animals without them seeing you. Of course you are a polar bear."
"but Dad, are you sure I'm a polar bear?"
"Yes, son. You have a big black nose for sniffing out food. Your nose means that you can smell things miles away and under the ice. Of course you are a polar bear."
"Oh Dad, are you definitely definitely sure I'm a polar bear?"
"Yes, son. Look at your big sharp claws for breaking through the hard ice and digging out food - and they help you swim in the icy cold waters. Of course you are a polar bear."
The dad looks at his son and says
"Why do you keep asking me, son?"
and the son replies
"Because I AM FUCKING FREEZING!"
