One of my favorite stories:
Babe Ruth was invited to the FDR White House for a formal dinner. He was seated next to Mrs. Roosevelt as the guest of honor with the president naturally at the head of the table. The first course was cooked asparagus with melted butter. Everybody tucked in except Ruth who only sat there and looked at his plate. Mrs. Roosevelt, noticing that Ruth was not partaking, turned to him and said, “Why Mr. Ruth, don’t you care for asparagus”? To which the Babe replied, “Nah, it makes my urine stink.”
Ronald Reagan was with Queen Elizabeth at Windsor Castle one morning, and since they shared a love for horses, they decided to go riding together. Some distance from the castle, as Reagan was following the Queen up a small grade, the Queen's horse decided to loudly expel gas in sync with each step.
Embarrassed, the Queen turned around and said, "Oh, I am so sorry, Mr. President."
"No problem your majesty," replied Reagan, "I thought it was the horse!"
