Now there's a driver who really wants to beat seven bells out of a certain wizard.
Do not meddle in the affairs of wizards, for they are subtle, quick to anger, and really don't like Polish trams. You've got to hand it to SA Wardega - catchphrase "insane people are the best!" - he knows how to get a tram driver's attention. Mind you, if ever there's a driver who really, really wants to beat Gandalf to death, it's this one!
At least Gandalf had a few friends on hand to help out, if things got a bit fraught. This isn't the first time Wardega's gone playing in traffic; this time last year he tried out his Slenderman routine, with about the same result. Good job nobody hit him, really.
If you've ever wanted to see what happens when this sort of thing goes a bit wrong, check out his Autumn Ghost, particularly about 1.12 in.
