There are a lot of wedding poems on Youtube. Some of the others are just terrible, most rhyme, some are funny, some are outrageous, some are sentimental (OK most are sentimental but that's OK)
This one above is far and away the best. It's called Long Distance Bike Ride by Andrea Hope
I also found a wedding poem generator, here. See mine. I really love it.
