Who invented the BJ??
I googled and all I found is this:
Arthur Blow (1023-1079) was an army leader in the Battle Of Hastings. The troops' morale was often low so he devised a cunning method of keeping spirits up by instructing his wife to orally service them as they waited in line. The troops, being grateful for such stress relief, referred to her daily doings as a Blow Job in honour of their leader.
Don't know if it's true though, share
