Man, when my company got shut down in the dot com days, after the 10am all hands, I said screw it and took my entire team out for drinks until about 4, out of my own pocket.
As far as I'm concerned, that's the way you do it if you're going down with the ship. Drink with the crew, pay for them, and tell stories and try to make plans as you slip into the waters. 19 years later, I'm still friends with all but one who disappeared to the offline somehow.
Ended up giving my director a slightly embarrassing hug when we got back in, but we'd been through enough over the past that she forgave me and we're still friends.
