What is your embarrassing moment?

I think my embarrassing moment was on my wedding day. My wedding was a time of true happiness and beautiful moment for me and my wife, except when I sang a song for her during the wedding. I have been practicing secretly for a very long time as a gift. I was singing very well until when I reached the climax of the song. I sung out of tune. People began to laugh. In order to change the atmosphere for my embarrassing moment, I made an ad-lib by saying, 

"Its okay everyone. Today my condition is not very well; I will do better next time."

Someone said, "Do you mean that you would be getting a divorce and remarry?" Everyone started laughing but this is my embarrassing moment.
