One subtle motif in the novel is Vonnegut’s use of the grotesque as a way of undermining and critiquing the elite, ruling class. Many of the names of things have a connotation that is either bodily or self-critical. Take the name of the supercomputer, for instance: EPICAC, which is close to ipecac—a drug used to induce vomiting. The subtext then, through naming the computer this, shows obvious disdain for the machines. 

Antiques are prized as relics of some bygone civilization in the novel, which is not altogether different from how they are seen today. There’s an inherent irony in the way that certain characters place value and worth on their antique things: Kroner on his shotguns, Anita on her furnishings. The characters fail to see that the happiness these objects give them they themselves are actively working to destroy.
