What's the worst fight you've overcome with your significant other?

Shortly after my husband and I were married, he came home very drunk. I was terrified, as the only drunks I knew in my lifetime were abusive. We fought about it and he tried to get closer. I was baking at the time and had an unopened five pound bag of flour on the counter and I threw it at him. He ducked and the flour hit the wall and exposed. That sobered him up real quick.
We never really had any big fights since then, luckily.
