Well you might have know from schools when you rub a hair-comb in some plastic cloth or wollen cloth and bring it close to pieces of paper the paper pieced lift up as they get attracted by the comb. This is static electricity. This is behavior of material with certain properties, like the other one current electricity where it passes through certain material like copper etc., and produces a shock as well.
Now when it comes to TV - the old cathode ray tube has got phospors to create pixes as the cathode rays impinge on them from the gun internally. One of the side effects, is as the tube is made of glass and glass is an electro static material with bombardment of electron constantly inside the tube, the glass outside carries a charge always. So your hair gets attracted..and you can try other electro static items as well - like light paper pieces etc.,
