     I guess, They did give one to the guy that invented the knock knock joke!   
      
   BTW, I invented that idea 51 years ago when I built a voltmeter. Oh   
   wait, maybe   
   that whole idea was in the text book for my 11th grade electronics class.   
   Let's see Basic Electricity Third Edition Paul Zbar, Copyright 1956.   
   Hmm, must have been   
   a decent teaching book as we got new copies in 1972, so it was around a   
   long time.   
      Oh geez, it wasn't me or Paul, Jacques-Arsène d'Arsonval and Marcel   
   Deprez   
   developed a meter with a stationary permanent magnet and a moving wire coil   
   in 1882. I'll bet it didn't take them long to figure out how stop the   
   meter from pegging. :-)
