The AKA forum has some hilarious stories in there wedding thread. I wrote one a few months ago about a Redneck wedding I went to but I'm too lazy to go find it.
I was invited to a friend's wedding a few months ago. She was friends with both my roommate and I. Now, let's say two people live together and are just roommates, how many invitations would you send? Everyone remember this rule of etiquette: unless they are a couple, you send an invitation to each person. She tried to make her wedding as cheap as possible so she sent a wedding invitation addressed to both "Ms. ZTAngel and Ms. ZTAngel's Roommate". Tacky, Tacky, Tacky. My roommate joked, "Since she sent us only one invitation, does that mean we only have to give one gift?" I thought about it but then decided that would be wrong of us. Instead, we got drunk at the wedding and started telling people that apparently we are now Lesbian Life Partners since the invitation was addressed to both of us.

On top of it, there wasn't a reply card in the invitation. The invitation (which had spelling errors by the way) had at the bottom the couple's email address for people to RSVP to.
The wedding itself was pretty bad, too, although not as bad as aephi alum's wedding horror story.
It has been a little over three months since the wedding. I am still waiting patiently for my thank-you card for the gift.
