An old gentleman I work with (sort of -- we work at the same institution, but I've only seen him for the first time today, in a communal office) just got up from him desk, put on his hat, and walked toward the door. On his way to the door, he mumbled something unintelligible (I heard only "mumble, mumble, go home....").
I stopped what I was doing and asked, "What's that now?" (Living down South, it's sometimes nice to throw the word "now" on the end of a sentence.)
"Let's pee on the fire and head on home," he said.
"Sounds like a good idea," I said.
"Only thing to do now," he replied, and walked out the door to face the rain and the coming darkness.
