Book recommendations : Negotiation skills etc

[ThomasSoerensen]

I'm looking to build up on Negotiation skills/knowledge and have just finished reading "Getting to Yes". It's a reasonably good book but one of those that isn't easy to read, i.e. not the most interesting or naturally flowing.

Can you recommend any other Negotiation books?

(I've put this in General so that we can all enjoy the customary humourous responses in addition to the serious ones...)

same guy made "Getting past NO"

Plan A : Have a good position/hand to start with
Plan B : Tell a pile of bs to convince everyone you have a good position/hand
