這不是废話嗎？
"Do you think he'll accept the job?" "Does a bear shit in the woods?"
"你覺得他會接受這份工作嗎？" "熊會在森林裡大便嗎？"
"Is the food good at this restaurant?" "Does a bear shit in the woods?" It's a no-brainer.
"這家餐廳的食物好吃嗎？" "熊會在森林裡大便嗎？" 這還用問嗎。
"Will he be on time?" "Do bears shit in the woods?" Of course he will.
"他會準時嗎？" "熊會在森林裡大便嗎？" 他當然會。
