lol! I once gave my physics teacher an electric shock... only a little one mind! I was always the one to be picked to demonstate the vandergraph generator cos of my long hair. He was telling the class how while i was stood on the plastic box with my hands on the generator (and my hair stood up on end) that i was electrically charged, and that i would be until i either stepped off the box or touched something to earth the electricity. At that point i felt the need to touch his shoulder, he gave me a very evil look and I just said "oh yeah! thats cool innit?". Not sure he was amused! lol!
