I think a truly great invention would be the Swedish Filter: a device one straps to one's head that activates automatically whenever one hears something one would rather not, and translates it all into Swedish, so one didn't have to understand it. I have one of these already. It kicks in whenever people talk about probability. Probability speaks to me in Swedish. Like the cafeteria in IKEA. And, just like the cafeteria in IKEA, I can forsee no other outcome to our interaction than my being pelted with meatballs.

I think that FOX News has been deploying Swedish Filters to their pundits for years now. They seem to be catching on.
