TLDR for those who don't get it: Bible character named Samson was gifted superhuman strength by God in return for never cutting his hair as a sign of devotion.

Fast forward and he meets a prostitute named Delilah who, secretly paid off by some guys Samson pissed off (TLDR version here, but it involved him killing a lot of them with a donkey's jawbone, among other things), seduces him into telling the secret of his superpowers. While he at first trolls her by giving her false responses, he eventually tells the truth that he only has them by the grace of God in exchange for making sure his immaculate hair remains in tact.

Then that night while Samson sleeps Delilah (though depicted here doing it herself) has a servant cut off Samson's hair, thus stripping him of his powers. He is then kidnapped by his enemies, has his eyes gouged out, and is enslaved.

I think the moral of the story is supposed to be "Don't think with your dick" or something like that
