Well my old principal had two.
One was called "Little Trouble (a smaller paddle) and the other was called "Big Trouble" which was...yes you guessed it.
My memory is poor but I think I got into "Little Trouble" once. I just remember not wanting to get into "Big Trouble!"
Funnily I ran into him about 10 years ago which would be about 40 years after the fact and he looked exactly the same as I remember!
Guess as a young child everyone over 15 yoa "looks old."
