I've got a good one, which I used for a toast at my brother's wedding. I got it off the internet so I can't claim to have written it, but I wish I had.
"My greatest wish for the two of you is that through the years your love for each other will so deepen and grow, that years from now you will look back on this day, your wedding day, as the day you loved each other the least."
I like the twist ending- it takes just a second to sink in.
"let me be the first to welcome our new insectile overlords"
