Step 1: Tell her you are a doctor, preferably successful and paid handsomely.
Step 2: Take her on a date to the fanciest restaurant in town.
Step 3: Keep a pair of hospital scrubs in plain sight in the back of your car.
Step 4: When she orders salmon and chokes on a missed bone, scramble and frantically yell "Does anybody know the Heimlich?" while your date's face goes blue as she hacks and fights for breath.
*Bonus Step 5: When she hits the ground from total loss of breath and starts to croak, be clueless as to how to go about performing CPR.
