I use swype. Yesterday, it autocorrected the word "sleep" to "Ashley" (conveniently, I dated a woman named Ashley about...oh...12 years ago).
Here's the problem...the message to my Fiancee was:
"I am getting into bed and going to f*cking Ashley"
...instead of "I'm getting into bed and going to f*cking sleep"
Lady No-san was, quite fortunately, amused.
