You get shocked touching a door knob because of the friction between the carpet and the soles of your shoes. By walking across a rug or carpet, your body starts to become negatively charged because of the electrons picked up from the carpet. When you go to touch the door knob, your negative charge repels the electrons on the door knob, making the knob positively charged (the door knob becomes positive because of the exchange of electrons to the hand).
