I have a funny story about autocorrect, though it didn't happen to me, it happened to my best friend. 

My friend's phone has been what she likes to call "going insane". No one really knows what's going on with it, but when she presses a letter on the keyboard for example, the phone will type in random letters and then autocorrect will correct it to something completely random. So, she was texting her good friend/crush, when her phone starts "going insane". She pressed a letter on the keyboard, and it typed in a bunch of other letters, then those letters were autocorrected into "I love you". She accidentally sent the words "i love you" to her crush. Of course, he did already know that she liked him and he knew that her phone was messed up, but it's still hilarious. To me at least.
