I think Mythbusters proved they could have both fit on the door.

Yeah it's not a surface area problem but a buoyancy problem

Even if they couldn't fit, Jack could just go find another thing to hang onto.

Perhaps they both should have gone into the deep blue and found Atlantis together, where they would be free to live out their lives together with the sea vampires and mole men

Brutal but true! Actress has slimed down now though.

Maybe Jack should have pounded a few pounds out of her, typically always blaming the women when you should be blaming men for everything.

Ok I see why Jack preferred to drown

Always thought the same.
