Caspar Weinberger (1917-2006) was the American Secretary of Defence between 1981 and 1987. Portrayed with suspiciously shark-like features, he was one of Ronnie's more long-suffering aides, and was mostly in charge of making sure Ronnie never started any unsolicited wars whilst his back was turned. Throughout his short appearance in the show, Caspar is voiced by John Sessions. In the Audience with Ronald Reagan sketch an audience member asks him "How's your asshole?". Reagan then answers and replies by saying "Caspar Weinberger's doing just fine!".
