Back To The Punchline

(My dad, younger brother and sister, and I are having dinner, with mom away for the evening. We end up discussing the Back to the Future series (this is a day after BttF Day) and what it predicted correctly.)

Dad: “Well, we don’t have time travel yet.”

Me: “Nor do we have flux capacitors.”

Brother: “But we can generate the required amount of gigawatts.”

Sister: *completely straight-faced* “Giga-what?”

Brother: *starts to explain before realising she’s messing with him*
