BCJ, the joke is in hosting the party without attending and requesting others to do the job of "hosting" while charging for the event.
It's like inviting guests over for dinner, charging them for the food and drinks, and asking them to bring their own knifes, forks, glasses, pots and pans....etc.. And then to top it off, you tell them you may not be there, so they also should bring a stove and dining room furniture. Oh, and BTW could someone pick up the food and drinks!
Now, doesn't that sound like fun!
I personally would decline that wonderful offer!
Maybe one of these years I'll tutor you in the art of "HOSTING" a tailgate party.
The key word is HOST. Look it up sometime!
It's like: "Hey you're invited, carry your ass, and have fun"!
BTW: it was a "private joke" until you demanded it become a public joke!
