Well I was going to come up with some random Star Wars related stuff of my own but I think I'll postpone that and follow up the whole "What was the plan for rescuing Han" with an equally valid question that was raised over at cracked.com

Was Jabba trying to go to war with the Rebellion?

He holds 3 high ranking Rebel prisoners hostage and never asks for a ransom. Luke walks in and says free my friends or die and he just laughs at him. When Luke proves he's not messing around by killing the Rancor and gives him another chance to free his friends without any more blood shed, Jabba refuses to listen and decides to execute the majority of his hostages in a manor that only serves to entertain him and his entorage.

Jabba's refusal to bargain with Luke gains him nothing and ultimately results in the loss of everything. Was he a criminal mastermind or an idiot?

My head is about to explode :o

I just go with the plot. However, Jabba did look like he had been smoking crack in every scene
