In the middle of the night...actually it was 3am in the morning, my phone randomly starting to play Westlife...and I couldn't turn it off. So I turned my phone off and the music continued! And I was horrified! So I threw it away, far as possible away from me and it continued, I tried everything, and it wouldn't turn off...eventually in the end I just had to sleep through the whole Westlife album playing before I could sleep again.
Not too scary because... I do the scaring.
