I guess I'm the pug jesus today. From wikipedia:

Before the speech, while Reagan was joking with NPR's audio engineers during a soundcheck, he riffed on his own speech, saying, "My fellow Americans, I'm pleased to tell you today that I've signed legislation that will outlaw Russia forever. We begin bombing in five minutes." This sort of levity was common for Reagan; he injected his humor into soundchecks, outtakes, and downtime throughout his careers in show business and politics.
