7Daily - Wanna fake marry?

Are there like, companies that specialize in this stuff? All that matters is that it looks like a normal wedding on the outside. The goal is to get back the congratulatory money my parents sprinkled around. Both of them have been in the workforce for a long time and have good jobs, so they've really been to a lot of weddings. The problem is I'm an only child and firmly childfree, so honestly I wanted to have a non-marriage ceremony, but I don't think that'll realistically help me get the money back... Has anyone around you been in this situation or done this???
