The Hip Bones Connected To…Nothing

(I am 7, and my 12-year-old sister and I are playing under our kitchen table. I crawl out from underneath, and she follows but her hands slip and she falls over.)

Sister: “Ow! I landed right on my side, I think I might’ve misplaced my pelvis!”

Me: “You’ve what your pelvis?”

(I start laughing hysterically at her mistake.)

Sister: “Don’t laugh, it’s really sore!”

(It then suddenly dawns on her what she said, and she starts laughing her head off too. My mum hears the noise and comes in.)

Mum: “What’s so funny?”

Me: “[Sister] has misplaced her pelvis under the table!”

Sister: “You knew I meant dislocated!”

(I’m now 26, she is 3. If she misplaces something, my mum and I still make the joke that it might be under the kitchen table with her pelvis.)
