OK, I confess. I was watching funny pug videos on Youtube. It was the Wonder Pugs video and I was just laughing like crazy when Crazy Pug went into action. He really doesn't like hearing things on the computer, it sends him berserker than usual. He leapt onto the computer box, which was sitting on its side, and pushed it over with a mighty thump.
The video stopped, went jerky. The screen went blue stripey shaky. I decided to reboot. It won't.
Bloody pug. Bloody computers. Thank heavens for the laptop.
