Winston words

Of late J has been using all sorts of new German words and expressions. This evening he was describing "die blecherne Stimme" of a robot. Yesterday he actually used "gewissermaßen" in a sentence, perfectly correctly. When I ask him where he's been getting these words, he says: "Das habe ich bei Winston aufgeschnappt." I think by now he's listened to the three Winston stories we have some 10-15 times each.
