Lyndon Johnson, after pissing on a Secret Service agents leg, said "That's all right, son. It's my prerogative."

 

LBJ once pissed on the legs of his Secret Service bodyguards and when challenged on this, LBJ said “That’s all right, son. It is my prerogative.” Prerogative is defined as “a right or privilege exclusive to a particular individual or class.”

LBJ was not only the president, he was also a prodigious urinator, who pleased himself by pissing on his Secret Service detail while shielded from public view, according to Mental Floss's Jenny Drapkin:

Johnson lived to dominate, and he used crass behavior to bend people to his will. At 6-ft., 3-in. tall and 210 lbs., he liked to lean over people, spitting, swearing, belching, or laughing in their faces. Once, he even relieved himself on a Secret Serviceman who was shielding him from public view. When the man looked horrified, Johnson simply said, “That’s all right, son. It’s my prerogative.”

 The stories I was told by ushers, maids and butlers during his Administration all ended the same way, “they were glad to see him go.” The White House is ran and maintained by the Chief Usher, his tiny office is right behind the elevator. LBJ liked to,stick,his head around the corner and bark orders, demanding almost instant compliance.
