Photobomber Trolls Tourists at Leaning Tower of Pisa [VIDEO]

Here's a perfect example of the good kind of troll -- the one who leaves no high five left behind. Everyone wants a special snapshot when they visit a historical monument like the Leaning Tower of Pisa, and Darius Groza wants to make sure visitors get that perfect image.

The prankster, who writes for Romanian blog JEG, runs into pictures and gives a big high five to tourists posing ironically like they're holding up the building.
