Alright, listen up, you chucklehead. So, you thought this was funny, huh? Well, let me break it down for you. Your brain is smoother than a peeled potato, so I'll go slow. The joke is about three famous politicians: Obama, Trump, and Clinton. They're on the Titanic, which, you might remember from history class (if you ever showed up), was a ship that sank. Obama, being all about saving people, says they need to save the women and children. Then, Trump, being... well, Trump, says 'Screw the women and children!' because he's selfish. Clinton, as usual, is being indecisive. It's funny because it plays on their known personalities and it's a ridiculous situation, you see? You're welcome.
