Chinese fire drill

A couple days ago I was stopped at a traffic light and saw a joke in real life. A Rav 4 pulled up next to me and came to a stop. Three Asian girls exited the vehicle, ran around the car, and then got back in through different doors. I thought it was a "Chinese fire drill" but under closer inspection all the girls were Vietnamese. The only reason could tell.....they all were wearing bibs and had little puppies under the arms who were frantically trying to run away before being given and extra hot pho bath in the kitchen.
