After reading recently that Abraham Lincoln might have been gay or at least bisexual, we were dying to know what other presidential secrets were kept out of our textbooks. To satisfy our curiosity, we contacted noted presidential historians to see what other dark secrets were out there. Here is what we found out:

Harry Truman: Liked to have Secret Service agents give him piggy back rides throughout the White House.

Richard Nixon: Was the inspiration for the Beach Boys' "Barbara Ann".

Teddy Roosevelt: Moustache was really a mink pelt he shot while hunting in Siberia.George H. W. Bush: A mama's boy.Gerald Ford: Secretly plotted with Henry Kissinger to steal Chevy Chases' nose.John F. Kennedy: While at Harvard was caught in bed with penguin.Dwight D. Eisenhower: Wanted the national interstate system to spell out "I Like Ike".Chester A. Arthur: Was afraid of the letter Q. Herbert Hoover: Would often refer to occasional bouts of constipation as the "Hoover Dam."Millard Fillmore: Always wanted to be a ballerina.Woodrow Wilson: A kleptomaniac; nearly caused an international incident when he tried to still some silverware from a state dinner at Versailles.Franklin Roosevelt: Once placed a whoopee-cushion in Stalin's seat at Yalta.Lyndon B. Johnson: Claimed his appendix scar was an escape hatch for his "Commander in Chief"

Ronald Reagan: Was ready to nuke the Soviets if the "Miracle on Ice" went the other way.

Bill Clinton: Wanted to open a library simply because he thought librarians were "smokin'"

Calvin Coolidge: Would hoard mashed potatoes in his desk.
