I'll go first. My cousin had a courthouse wedding last fall. None of the family was invited. Fine. Then they had 2 receptions near home. One with his dad's side, one with his mom and her friends. Then, the couple proceeded to travel around to their out of town families. They hijacked the bride's aunt's 25th wedding anniversary party. Invited themselves and turned it into a joint celebration. Then they hijacked the groom's family Thanksgiving reunion and had a second reception with them. They kept bragging because they saved so much money and no one had to travel. The groom's mother texted her sisters before Thanksgiving to remind them to bring a gift from registry. It did not occur to them at all that their choices could be perceived as rude. Especially the hijacking of someone else's well-hosted anniversary party. The photos were non-pro 4x6's. They changed into cartoon character outfits after the ceremony.
I'm sure there are way worse stories out there!! Let's hear them.
