You're too funny!  I love it when we have to write his name on labels;
people scream that the S hasn't got a period, or that it does (S.).  So
out  comes the almanac.  So do we follow proper grammar rules or what.
And on it goes.  For my part, I just do what the Harry S. Truman Library
does, put a period after the S.
