I have a little collection, looking to expand in the future.
I loved Bret's book. Just has the feeling of being genuine and straightforward with amazing stories.
Jericho's A Lion's Tale was also excellent. I loved the approach and can't wait to read the new one.
Angle's book wasn't bad at all. It was amazing to read some of the things he's been through.
I thoroughly enjoyed Roddy Piper's book too. In the Pit With Piper was a good read.
Also recommend the two Bobby Heenan books.
I haven't read many bad ones, really. So far I have the above, Lawler's, Mick's Have a Nice Day and Harcore Diaries, Rock's (alright), Broken Harts by Martha Hart, Chyna's (meh. Bought it way back when it first came out) and a couple of Ventura's political books. Jesse's always a decent read. I also have the Dynamite Kid book and Lanny Poffo Wrestling With Rhyme but haven't read those two yet. (Got 'em both for 2 bucks apiece. The Poffo one has signatures in it, but don't know if they're legit or not. Lanny's looks legit, but Randy's is in there too and it don't appear to be his from what I can tell.)
I want to get more of the older wrestler's books. I'd like to get hold of the Brody book even though it wasn't an autobiography. The ones Dyno Kid listed I'd like to get hold of too (Brisco, Anderson, Stampede, and Dillon). Heck, I'd even like to get Exotic Adrian Street's book.
I don't know about Flair and HBK. Those two don't seem like they'd be too humble IMO. I'll probably get them just to have, and will read them, but I'm not a big fan of HBK in a behind the scenes type aspect and I think Flair's would be a little too self-glorifying. But I'll try 'em.
Damn, the way I post, maybe I should get off the forums and write a book myself.
