Tras el superventas "Farts Around the World" llega la respuesta en forma de eructo.

Following the bestselling Farts: A Spotter's Guide series (over one million copies sold!), this hilarious field guide covers 10 different types of belches through text, illustrations, and sound.

Filled with shameless body-related humor, Burps: A Connoisseur's' Guide identifies the characteristics, habitat, voice, and tasting notes" of each gassy oral emission.

The sound of each burp is reproduced with alarming accuracy through an attached battery-powered belch machine.
