Well, I don't remember it ever being extremely hilarious... like roll on the floor laughing, but I'd still give it a read. It can be funny at some points, but it's still a very entertaining book to read. That's coming from someone who doesn't read.
I don't know if you've ever heard of Tucker Max... but he had a website that became extremely popular, much like Maddox. He decided to write a book. I haven't read that yet, but it should be pretty funny as most of his stories are.
It's called "I hope they serve beer in hell" and his website is
TuckerMax.com where he has a bunch of his stories posted.
