bathroom humor

For weeks now, I've been seeing this sign, and I haven't known what it means. There's a small bar we often go to, and in the bathroom, there's a sign that you see as you squat.
It says: 来得匆匆，去得冲冲。

Every time I saw it, I wondered what the hell it said. "Come something something, Go something something." What does 匆匆 and 冲冲 mean??

I finally figured it out: "Come in in a hurry, leave excitedly!" hahahahaha
