Xiang Yu had Liu Bang's father held captive and hoping to get Bang to surrender, sent him a message "I've got your father and I'm going to boil him alive"
Liu Bang's response was "be sure to send me a cup of the soup"
prolly not the best relationship between those
(For what it's worth, Liu Bang's father was not boiled alive, Liu Bang won the contention for the throne and became the founder of the Han Dynasty, Xiang Yu uh, had a less good time)
