Half asleep in frog pajamas

I just don't know about this book. It was funny at times, and had occasional bits of quirky Vonnegutian wisdom, but mainly it seemed mean-spirited. Like it was written in second-person with a basically unlikeable protagonist, so reading it made me feel unliked. Is Tom Robbins trying to test my empathy? Or is he just kind of a jerk? I just don't know.
