A few years ago, I did a consult on an 80 year old patient had a bleed in his head that was caused by a fall. I asked the son (who didn't speak perfect English) how his father had fallen.
Son: "It was one of those... those things you jump on..."
Son: "You know, for parties. You jump on it..."
Me: "A... trampoline?"
Son: "Yes, a trampoline."
Me: "Your father got hurt jumping on a trampoline??"
