Russel's personality

We are led to believe within the wiki and the in Rise of the ogre that Russel is supposed to be known for his polite manners and well speaking abilities, so why does he have broken grammar and racial vocabulary in the those animated shorts? If you don't know what I'm talking about, refer to "The eel", "Jump the gut" and "Fancy dress."
