Host a party for a charity

There are several ways to do this. You can simply put out a donation tin whose contents will go to a particular charity. You can arrange for donations of food and drinks to your party, so that guests' payments for these refreshments go to the charity. You can dedicate an upcoming event, like a bat mitzvah, graduation or bachelor party, to the charity so that donations to the organization are made in lieu of gifts. Whatever option you choose, you can feel virtuous about your debauchery - a very good thing!

Effort involved: no more than the effort of hosting any other party.
