The Adventures of Paddington Bear S03E26 - April Fools

Mr. Curry thinks Paddington's made him an April Fool, so he retaliates by sending Paddington on a fool's errand. Poor Paddington does not even know what April Fool's is. Aunt Lucy always taught him it was rude to play tricks on people. But in this case, Paddington's honesty turns out to be the best trick of all.
