By the way, do you think that the operation called a caesarean (cesarean) section has anything to do with Julius Caesar? Read more about this very controversial subject at the "caesarean section" page.
Thirty days hath September,

All the rest have thirty-one
Excepting February alone:
Which hath but twenty-eight, in fine,
Till Leap Year gives it twenty-nine.
