Do you have any funny auto correct text message moments?

I have heard about the famous auto correct on iPhone that causes people to inadvertently type something and send it without realizing what they are sending, as seen here.

Has this ever happened to you and what was the other person’s reaction? I don’t have an iPhone or Android so I wouldn’t mind hearing other peoples’ experiences with this.
