It was the weekend before the Presidential Inauguration and the staff of the White House was conducting tours.
As the guide was showing one group of tourists the Presidential portraits in one of the historic halls, a door burst open and a large aquatic sea mammal, balancing a beach ball on its nose, scurried past.
"My, what was that?" asked a woman in front of the pack.
"What else?" replied the guide. "That's the Presidential Seal!"
