One thing that I was thinking was that it would be funny if someone that you didn't like was getting married. Figure out who the venue is and who is doing the catering. Call the catering company saying, "Hey sorry to spring this on you guys last minute, but I realized that there is a HUGE typo in our catering order! The wedding isn't on Saturday; it's on Sunday!!! Please fix this so you show up on the right date!"
So Saturday comes along and the people show up to the wedding, and there isn't any fucking food. Next day some random hotel event gets a shitload of free catering dumped on them.
You could do this with photographers, florists, and so forth.
Or when all else fails, you could call the event venue itself and say you can no longer stay there because you believe in traditional values and saw that the venue allows business from queer homosexual deviants. When they are like WTF no just keep going off on how queers are ruining America and how Obama is a secret Muslim, and eventually get the wedding party kicked out for real for causing such a ruckus. This probably only works if you're in a liberal city...if you're doing this in Texas or something just do the exact same thing but say that you can't stay there because they host Christian events and you're tired of your fellow trannies being oppressed and that people need to check their cisprivledge.
