Samurai slices baseball

Rico's friend Kelley forwards this Mashable article by Olivia Nyland:

Rico says it reminds him of an old joke:

Two samurai are having a drink at a roadside inn. Bothered by flies, one draws his wakizashi and cuts one in half on the wing.
The other samurai pulls his sword and cuts, but his fly continues flying.
The first samurai shakes his head: "You did not kill it."
"No," the second samurai replies. "But he will not reproduce."
