Not me but my BIL's highschool reunion. A guy that was severely bullied in highschool started a Facebook group to get the ball rolling on planning a highschool reunion, he planned the venue, food, drinks and asked everyone pay a ticket price to cover it all.
He organised the money go into a provided bank account, received 200+ peoples HS reunion dollarydoos and fucked off. Never to be heard of again.
Ive never laughed so hard in my life.
