An American Borscht Belt comedian goes to perform in London England, which back in those days had theaters which accommodated a variety of acts, and he was really bombing.
Really bombing, and the audience was letting him have it, so in his desperation he yelled out something like “Fuck the Irish! Am I right?” and the audience agreed so enthusiastically with that that they stated to tear the theater apart.
Cut to the manager hustling the comedian backstage, where he tells him that he can cover the actor up with a big coat, and smuggle him out the back. But the comedian says no, he thinks that he has a feel for the audience now, and will do better in his next show. Which has the theater manager yelling for his digitalis, he feels his heat exploding, lol. Bruce did both their voices in his act, and it reads as being very funny. I had a book that included a transcript of some of his routines.
Anyway, our politicians are that comedian. When they’re bombing, and desperate, they yell out to the voters a message equivalent to “Fuck the Irish!”.
