A Touch Of Humor - From The Groom
Remember to inject the toast with your personality. If you're naturally funny, your toast should be too or else it will come off as unnatural. Here's a great example of how add a little humor to your speech:
I'd like to like to thank you all on behalf of my wife and I for sharing our special day. We've been worrying about this day for months and it means so much that you managed to make it and we hope you're all having a great time.
