Didn't Think This Through: He made a spur-of-the-moment oath to God that he'd sacrifice the first thing that exited his house if the Lord gave him a victory. He won, and the first thing that stepped out was his daughter.
Badass Israeli to be more specific. He is the strongman of Jewish myth.
Bond One-Liner: Upon killing one thousand men with a Donkey's jawbone, he made a pun on the fact that "donkey" and "heap" are homophones in Hebrew. Methods of translating this wordplay vary.
Bond Villain Stupidity: The Philistines could've killed Samson easily after his hair was cut, but instead they blinded him, imprisoned him, and put him work grinding grain to humiliate him. They came to regret it.
Breakout Character - He is the only Judge to have a movie made for him, among other things.
Dying Moment of Awesome: "And Samson said, Let me die with the Philistines. And he bowed himself with all his might; and the house fell upon the lords, and upon all the people that were therein. So the dead that he slew at his death were more than they that he slew in his life."
Fake Weakness: He made up several of these to tell Delilah, after she asked the secret of his strength. Somehow he never figured out why, whenever he told her one, some Philistines would always try to use it on him...
Humiliation Conga: When the Philistines captured him, they blinded him, imprisoned him, and put him work grinding grain. They then brought him out to mock him, and have him perform for them. He gets the last laugh, though.
Messianic Archetype: The subversion of the type. His birth is announced by an angel and raised a Nazarite (puritan Hebrew) yet broke its traditions simply because he was the Chosen One, his battles are more like the antics of a super powered college prankster and his motivation to finally beat the Philistines was personal revenge.
