Most tourists can’t resist taking pictures of themselves, pretending to hold up the Leaning Tower of Pisa in Italy. Not if Romanian blogger Darius Groza can help it. Interrupting many moments of cliched photography, a video of a bespectacled Groza weaving in and out of the frame, high- fiving unsuspecting posers, has gone viral. Groza, 25, who writes for the blog JEG, calls it “troll high- fiving” and has advised fellow pranksters to be careful with tourists who climb on the chain fences surrounding the landmark. The video already has 1.4 million views on Youtube.
