Let sleeping dogs lie. Words to live by, unless of course you have a tram full of people to drive someplace and the dog is sleeping on the tracks.
Luckily, since almost everyone in the former Soviet bloc has a video camera, we get to watch the fun as the driver tries a number of different tactics to get the dog to move. Whatever the case may be, that must have been a really sleepy dog. It took almost five minutes to get it out of the way.
