John Quincy Adams – Alligator
John Quincy Adams may have been a serious leader, but he clearly wasn’t afraid to let the White House run wild.
The former president of the United States was once given a 500lb, 12-foot alligator as a gift and he kept it in a huge bath tub in one of the unfinished White House rooms.
Sources report that Adams used to enjoy showing the scary-looking animal off to disbelieving, petrified White House visitors. But after several months the gator was moved to a different home.
