"Annoying, Nasty Tone Ruins It"
This guy can be funny at times--though after a short time, his humor starts feeling really formulaic--but what really makes this unpleasant to listen to is the tone. It's like listening to the worst, angry, blowhard, frat-boy you can imagine.
And most of the times, he's just not 1/10 as clever or funny as he thinks he is. (An example, is repeating gag of him asking the recording engineer for some water, which, if you listen to audio books a lot, has the potential to be funny, but just turns out predictable and stupid.)
