A polar bear decides to go to the beach as it is a nice sunny day, after driving for a few hours he almost arrives at his destination then he notices that the oil pressure on his car has started to drop, luckily he noticed he had just driven past a garage so he turns the car round and pulls in, he tells the mechanic the problem, the mechanic tells the polar bear to go off for an hour or so and then come back as he should then know what the problem is. So the polar bear decides to go for a walk down the beach, an hour later the polar bear returns to the garage and find the guy looking at his car, the mechanic says "Looks like you've blown a seal" to which the polar bear says "No I've just eaten an Ice cream".
