A rabbit one day managed to break free from the laboratory where he had been born and brought up. As he scurried away from the fencing of the compound, he felt grass under his little feet and saw the dawn breaking for the first time in his life. 'Wow, this is great,' he thought. It wasn't long before he came to a hedge and, after squeezin under it he saw a wonderful sight lots of other bunny rabbits, all free and nibbling at the lush grass. 'Hey,' he called. 'I'm a rabbit from the laboratory and I've just escaped. Are you wild rabbits? 'Yes. Come and join us,' they cried. Our friend hopped over to them and started eating the grass. It tasted so good. 'What else do you wild rabbits do?' he asked. 'Well,' one of them said. 'You see that field there? It's got carrots growing in it. We dig them up and eat them.' This, he couldn't resist and he spent the next hour eating the most succulent carrots. They were wonderful. Later, he asked them again, 'What else do you do?' 'You see that field there? It's got lettuce growing in it. We eat them as well.' The lettuce tasted just as good and he returned a while later completely full. 'Is there anything else you guys do?' he asked. One of the other rabbits came a bit closer to him and spoke softly. 'There's one other thing you must try. You see those rabbits there,' he said, pointing to the far corner of the field. 'They're girls. Let me tell what we do together with them .......... Go and try it.' Well, our friend spent the rest of the morning working his little heart out until, completely knackered, he staggered back over to the guys. 'That was fantastic,' he panted. 'So are you going to live with us then?' one of them asked. 'I'm sorry, I had a great time but I can't.' The wild rabbits all stared at him, a bit surprised. 'Why? We thought you liked it here.' 'I do,' our friend replied. 'But I must get back to the laboratory. I'm dying for a cigarette.'
A team of archaeologists was excavating in Israel when they came upon a cave. Written across the wall of the cave were the following symbols, in this order of appearance: A woman, a donkey, a shovel, a fish, and a Star of David.
It was considered a unique find and the writings were said to be at least three thousand years old. The piece of stone was removed, brought to the museum, and archaeologists from around the world came to study the ancient symbols. They held a huge meeting after months of conferences to discuss the meaning of the markings.
The President of the society pointed at the first drawing and said: "This looks like a woman. We can judge that this race was family-oriented and held women in high esteem. You can also tell they were intelligent, as the next symbol resembles a donkey, so, they were smart enough to have animals help them till the soil. The next drawing looks like a shovel of some sort, which means they even had tools to help them. Even further proof of their high intelligence is the fish which means that if a famine had hit the earth, whereby the food didn't grow, they would take to the sea for food. The last symbol appears to be the Star of David which means they were evidently Hebrews."
The audience applauded enthusiastically. But then a little old man stood up in the back of the room and said: "Idiots! Hebrew is read from right to left. It says: "Holy Mackerel, Dig The Ass On That Woman!"
