I have given myself an honoree doctorate so that I may carry out some scientific evaluations on the new paddles provided by the faithful Kodders. These are rather nasty implements and I want to know which of these gives the most . I have a new victim and he agrees to be the subject bottom for me to try out these formidable implements on. He does not like either of them but which will get bottom marks?
