I finished this book this week. Quoting from my LibraryThing review:

‘m not sure if I found this book amusing because of its inherent goodness or because I dated a Russian for five years, and–boy howdy–this really has certain things about that culture dialed in, at least from a humor vantage.

Part “Borat,” part “Everything is Illuminated” (Jonathan Safran Foer), this book keeps the butchered English and ridiculous hijinks flying at you at the expense of any sort of plausible plot. It’s raunchy, it’s irreverent, it’s the travesty of the Second World in the limelight.

Absurdistan, of course, doesn’t really exist. But that doesn’t stop Shteyngart from pretending it does and sending our protagonist, the 350-pound son of a recently-offed crime boss, there to flounder through various life-threatening, world-peace-threatening adventures.

Funny. Shameless. Somewhat tiring by the end.
