Duke: Good evening, fellow Republicans! I've got think this through! Why am I talking to an auditorium full of mutant sheep? I bring you greetins from the People's Republic of China? What are you saying?! These people are lifelong reactionaries! My subject for tonight is "our friend, that amphetamine." You twisted maniac! Now you've done it! They'll tear you limb from limb! Er... I mean, "why can't Johnny Blink?" Too late! Here they come!
