Candles

I've seen some really funny weddings because of candles. I've seen candles that wouldn't light, candles that nearly explode with flame, candles that burn for a few seconds and then fizzle. I've seen brides break down and cry over candles, flush with anger when candles wouldn't light, and toss candles away in disgust.

And yes, I've seen sleeves catch on fire and, on one terrible occassion, a groomsman's hair went up in a poofball of orange flame.

Cost of wedding? $10,000.
Memories of seeing a groomsman catch on fire? Priceless!
