Grover Cleveland's head

Grover Cleveland was an US president from 1885 to 1889 and from 1893 to 1897. In the 31st century he is kept as the Head Museum with the others formers presidents. Strangely, the museum kept two heads for his.

Trivia

 * Cleveland is the only president to serve two non-consecutive terms (1885–1889 and 1893–1897) and therefore is the only individual to be counted twice in the numbering of the presidents which explains why the museum had two heads of his.
