Bill Maher said this quote

After September 11th, I never much liked the trend of everyone and his brother wearing the hats and jackets of the NYPD and FDNY. Only the people who do the job should get to wear the hat. Would you wear someone else's Medal of Honor? Yes, it's a tribute, and sincere tribute is always appropriate for these brave people. But wearing their symbols is also rubbing off a piece of heroism that isn't yours.
