7th President: Andrew Jackson, 1829
Cow = 7 (Jackson was the seventh president)
Michael Jackson = Jackson
Phone up = 829 = 1829 became president
Hands = Handy Andy = Andrew
The cow (7) wanted to dance like Michael Jackson (Jackson), so she decided to phone up (829 = 1829) and ask him how to do it.
Connect Jackson to Andrew:
Michael Jackson (Jackson) could even walk on his hands (Handy Andy = Andrew).
NOTE: The way Mammoth Memory remembers Andrew/Andy is to think of Andy Hand, or Handy Andy. Anything to do with hands can then be related to Andy.
