9th President: William Henry Harrison, 1841
Bee = 9 (Harrison was the ninth president)
Hairy son = Harrison
Fart = 841 = 1841 became president
William Shakespeare = William
A bee (9) had a hairy son (Harrison) who did a fart (841 = 1841) on stage which flew up his long hair...
Connect Harrison to William:
...but the hairy son (Harrison) carried on and gave his rendition of William Shakespeare (William).
NOTE: The way Mammoth Memory remembers William is to think of William Shakespeare.
