He originally posted this in GQ, and went to the trouble to note that this situation would be in the state of California (establishing jurisdiction). Neither of those imply a manners question to me.
Your question reminds me of a time in college when I brought my football player boyfriend and his football friends to a party being thrown by the emo alternative kids. The football players got drunk and violent and none of the alternative kids could get them to stop or leave.
What ended up working best was a chain reaction of sorts. My friends asked me to get the football players out, I, in turn, asked my boyfriend to get them out, my boyfriend got the soberest of his friends to herd the drunker ones out, and in about ten minutes the guys were wrestling each other on the lawn and were no longer the emo kids’ problem. (They were Campus Safety’s problem.)
Putting drunk folks out of your house is not a good solution… if they drive and hurt anything/anyone, they could sue.
Give them a pillow and go to bed.
If they’re not impaired… may I throw Yoko Ono and William Shatner into the “frighten them out” music mix?
The Wreck of the Edmund Fitzgerald performed on bagpipes and accordion with vocal accompaniment by William Shatner? *
I think you’d be better off using a big-screen TV and surround-sound system to play Leonard Nimoy singing the Ballad of Bilbo Baggins. If that won’t scare 'em off, nothing will.
Stock a junk drawer with a pair of ski goggles & a paint respirator well before the party.
Place a broom by your back door.
At the time you are done with the party, send everyone who lives there (and who you love) upstairs to bed.
Tell the guests you are going to cook up your ‘trademark breakfast’ in the kitchen.
In a hot skillet, drop 1 stick of butter cut in quarters and then throw in a bowl of sliced Habanero peppers.
As Cloud Plume develops, grab and securely place on goggles & paint respirator while grabbing the broom.
As guests start hunching over coughing and crying, beat them with the broom and chase them out the front door while you scream “F-cking Hippies! I’ll Teach You Not To Go To Vietnam!!!”
Lock the door when you’re done, dead-bolt as needed.
Retro. It never goes outta style.
What about Pat Boone’s “In a Metal Mood?” It’s got to be good for something. (Of course, I don’t think I’d want to be seen buying it, that’s the problem…)
