Sticky Keys plays in reverse!

So randomly today, after I accidentally activated the Sticky Keys thingy to pop up, when I tried to close it, it wouldn't close and it "not responding"-ed on me. So then a bit after, while cleaning white stuff off my computer, it played the Sticky Keys sound IN REVERSE. After, I googled, but found only PDFs after videos after help articles that were completely off-topic. So I came here and am asking "What happened and has this happened to anyone else?".
