What did Bubb Rubb say, "Woo-Woo"? That's some funny sh**. I think that's downright retarded, but let's not forget that as soon as a 'Harley goes by, you wont be able to hear the whistlers....let's work on getting rid of that annoying crap, too. I'm afraid if I really speak my mind on those whistle tips and the idiots who would want them, I'm bound to start offending people....but man, is that dumb.
