It makes sense that the early Olympics included discus, javelin, and shotput. They were really trying hard to come up with new sports, and it showed.
"I've got a new one. You take this thing, and you throw it as far as you can, and then you see who threw it the farthest."
"We've got that one already."
"This is different. Are you ready for this? It's not a spear. It's not a disc. You throw a ball."
"A ball? Anyone can throw a ball."
"Yeah, but this one will be really heavy."
