Jungle.
A chimpanzee was walking through the the jungle when he saw his old friend the hyena.He asked him how he was keeping and the hyena said he not so good ,I'm sick to death of that bloody lion every time he see's me he kicks seven bells out of me.So the chimp said I'll climb this tree and you wait at the bottom and when the lion turns up and starts beating you up I'll jump down and we can two him.The hyena said it was a great idea and sat down under the tree.A little while later the lion turns up and starts kicking the living daylights out of the hyena then brushes himself down and walks off into the jungle.Two minutes later the chimp jumped
down from the tree, the hyena said I thought you was a mate of mine and you were going help me beat up the lion why didn't you help and the chimp said you were laughing that much I thought you were winning.
