Say what you want about President G.W. Bush, but one thing he isn't is a generic permanent marker user. The U.S. News and World Report recently highlighted Pres. Bush's outspoken respect for the Sharpie marker for its bold, statement-making mark and its ease of use. Bush often carries a Sharpie with him on his person (for autograph signing) and even has special Sharpies made up to give as gifts on special occasions.
The president of Sanford Brands North America, which produces Sharpie, summarizes it best, saying, "it's pretty cool" to supply the President with his writing utensils. It's rumored that Bush even gave out Camp David Sharpies with his signature on the side as a commemorative gift. Now THAT'S what I call peace-marking!
