Human: How does Pnin differ from Humbert Humbert? Assistant: 
Pnin differs from Humbert Humbert in many ways. Pnin is the anti-Humbert in every sense. Where Humbert flatteringly depicts himself as tall, handsome and charming with perfect English, Pnin is relayed as stubby, rotund, odd-looking and with comically bad English. In their respective stories, Humbert seduces with secret monstrosity, while the seemingly vulgar Pnin is a saint in disguise.
