Prejudiced

I went shopping at the downtown Macy's and there was a guy dressed in a Ku Klux Klan robe standing on the corner. "Whoa, I've got to see what he's up to." I walked over and he had a large tray with a big sign that said Free Cookies. "What are you doing?" "I'm giving away free cookies." All I could think of to say was "Are they any good?" His reply: "They're really good, but I'm prejudiced."
