Humor: figs in Afghanistan, kumquats in Kuwait

My high school honors math teacher (Bro. Walter Schreiner) used to say sometimes in response to a student's attempt at a proof, "Well, both my grandmothers are dead, but what does that prove?" Since then (for more than 30 years), I've been plying my own coined non-sequiturs: "What's that got to do with the price of figs in Afghanistan?" and "What's that got to do with the price of kumquats in Kuwait?"
