Not a good time to talk business

　　The banker fell overboard from a friend's sailboat.

　　The friend grabbed a life preserver, held it up, not knowing if the banker could swim, and shouted, "Can you float alone?"

　　"Obviously," the banker replied, "but this is a heck of a time to talk business."

　　注：float可以表示“(公司或企业)发行(股票)上市”。
