A pledge of allegiance to a cup of coffee is shown on many images:
   
“I pledge allegiance to the cup that holds my caffeinated beverage. And to the drink which it contains, one container, full of coffee, indispensable, with energy and caffeine for me.”
 
The cartoon was posted on Twitter by Marshall Ramsey on October 25, 2013.
 
     
Wikipedia: Pledge of Allegiance
The Pledge of Allegiance of the United States is an expression of allegiance to the flag of the United States and the republic of the United States of America. Such a pledge was first composed, with a text different from the one used at present, by Captain George Thatcher Balch, a Union Army Officer during the Civil War and later a teacher of patriotism in New York City schools. The form of the pledge used today was largely devised by Francis Bellamy in 1892, and formally adopted by Congress as the pledge in 1942. The official name of The Pledge of Allegiance was adopted in 1945. The most recent alteration of its wording came on Flag Day in 1954, when the words “under God” were added.
