When it comes to love, weddings are one of the biggest milestones possible. They're joyous celebrations that have the potential to be magical. However, sometimes things don't always go as planned and weddings can be more disastrous than planned. Bridezillas, runaway grooms, and of course, the unwanted guest all have the potential to turn a once-in-a-lifetime day into a real-life nightmare.

Just like in real life, TV weddings are one mistake away from going from dreamlike to a nightmare. Some TV wedding specials soar above the rest, becoming one of the most-watched episodes of the show.
