Q: What do you call an American drawing?
A: Yankee doodle!
Explanation: There is a famous American song titled Yankee Doodle Dandy and a well known poem with a similar name. A doodle is a drawing, like you might make in your school notebook.
This joke is funny because an American drawing might be called an American doodle; Yankee is a name for an American, especially during the Revolution.
Happy 4th of July to the folks in the U.S. and those traveling overseas.
