Historic Trivia: Fact, Legend or Pure Fiction?

Here are a couple of excerpts labeled "historic trivia" that came my way.  I won't try to corroborate it as factual or debunk it as legend or pure fiction.

Just posting it here on The Quest for Common Ground for the sake of humor.

Feel free to judge the material as having any truth to it or not.

The following text appears to be from Pete Thompson of Classic Designs.

• "Did you know that the saying "God willing and the Creek don't rise" was in reference to the Creek Indians and not a body of water? It was written by Benjamin Hawkins in the late 18th century. He was a politician and Indian diplomat. While in the south, Hawkins was requested by the President of the U.S. to return to Washington . In his response, he was said to write, "God willing and the Creek don't rise." Because he capitalized the word "Creek" it is deduced that he was referring to the Creek Indian tribe and not a body of water." 
• In George Washington's days, there were no cameras. One's image was either sculpted or painted. Some paintings of George Washington showed him standing behind a desk with one arm behind his back while others showed both legs and both arms. Prices charged by painters were not based on how many people were to be painted, but by how many limbs were to be painted. Arms and legs are 'limbs,' therefore painting them would cost the buyer more. Hence the expression, “Okay, but it'll cost you an arm and a leg.”  As all artists know, hands and arms are more difficult to paint!
