I've been kegging for a few years now and this reminds me of a story...
I started Kegging because I wanted to knock off Guinness and I had to have nitrogen. I built my kegerator or keezer and started with CO2 for my first kegged batch a lawnmower blonde. Then tried my Guinness clone and added a Stout Faucet.
On the first night hooking up my Guinness Corny, I didn't finish the connections for the faucet and left the gas on at pressure.
It was late, I went to bed and I didn't notice the poppet was leaking slightly. For whatever reason, I woke up in the middle of the night and can tell you that 3 gallons of Guinness on your floor at 3:00 am is not a pleasant sight. I lived in an apartment at the time and was on the second floor. The neighbors below never complained, but I'd imagine the and ants loved it.
