Beasts look so nice after few drinks… that you can’t stop climbing into a giraffe's cage.
But the prank went wrong when the 1.3 ton animal flew into a rage and attacked the three student trespassers at a zoo in Lithuania on Monday night.
Ruta Greiciute, a 22-year-old student at Kaunas Technology University, was hospitalized with a broken collar bone and nose after the nine-year-old male giraffe, named Solut, attacked her.
The other students survived the incident unscathed.
"This was a very silly thing they did. The scared giraffe could have stomped her to death," Kaunas Zoo spokeswoman Angele Grebliauskaite said.
The zoo reported that many animals had been disturbed Monday night as students celebrated a festival in a nearby condominium.
Police have launched an investigation to find out how the intoxicated students entered the zoo at night and climbed the 3.5 meter (10 foot) high fence surrounding the giraffe cage.
The head of the Voronezh region, Alexander Gusev, confirmed the death of Major General Vladimir Zavadsky.
