PIC BY KEN HADFIELD / CATERS NEWS / ANIMAL PRESS This is the hilarious moment a cheek-y bear decided to bare all in front of a crowd of stunned onlookers. After causing chaos by play fighting with his pals the naughty bear appeared to take a break from his mischief by climbing a nearby tree and crashing out. But then he went one step further by bending over and flashing his behind at the group of visitors at Yellowstone Bear World in Idaho, USA, who couldnt contain their laughter at the rude display. Award-winning photographer Ken Hadfield was right below the bear in the middle of the crows but was the only onlooker who managed to capture the bear looking right into his camera. *** Local Caption ***
