TLC has this new show called Four Weddings. It's baout 4 brides and they have to go to each other's weddings and vote of them to see who gets a dream honeymoon at the end of it.
Anyways, one of the brides on the show made yay flags for her wedding. Got some wood sticks some white fabric and spray painted "Yay!" on all of them. It was hilarious. Especially when one of the visiting brides asked, "what do we do with this?" If you ever get a chance to watch it, it's pretty good, especially the snarkiness that goes on.
