Once upon a time, a Chinese partner invited me to have dinner with a friend who had never eaten bullfrogs. So he asked what it was? The partner said it was chicken. So the friend jumped down. When he ate, he doubted why there were tiny bones in the chicken? So after dinner, on the return car, he asked me, what did I eat just now? I told him it was a bullfrog, so he stopped the car, pushed the door open and vomited.
