Man, that ones like that Batmans Mothers day card. its got a joke.. but its based on something so famous, that contradicts the joke that you really have to scratch your head.
Batman, very expressly has dead parents. very very famously so.
Alfred Nobel invented Dynamite. as in, the creator of the NOBEL PRIZE. you know, a very famous person. He died peacefully, after suffering a stroke. He did not die from a dynamite explosion. His younger brother actually died from a nitroglycerin explosion in a factory. Which lead to Alfred inventing Dynamite, expressly because it was safer. the entire POINT of dynamite was a means to protect, and stabilize nitroglycerin so it would be LESS explosive. so, he did not invent an explosive, he invented a safe means of transporting an explosive.
