One question too many

AS you know if you live near one, foxes are always asking questions. A wild boar was sharpening his tusks against a tree trunk one day, when along came a curious fox. "oh, dear," groaned the boar under its breath. "This fox is always asking silly questions. He'll drive me mad one day." whatever are you doing?" asked the fox, without saying "Good morning" first. "How odd," replied the fox. 'Why do you want to do that?" "To stop a them asking stupid question," snapped the boar, and tossed the fox into the top of the tree.
