What was funny was that while I was in the recovery room, waiting for the signal that I was recovering (i.e., releasing the air which they had put in to my colon for the test), I could hear the nurse in the cubicle next to me talking very loudly to an obviously half-deaf patient. "Well, sir, have you passed any gas yet?" "What?" "You need to pass some gas before you try to sit up, sir." "What?!" "No, sir, please, stay there until you've managed to pass the gas." "What?" "LOOK, MISTER, YOU CAN'T GET OUT OF BED UNTIL YOU'VE FARTED, OKAY?" "Oh... why didn't you say so?"
