Two animal researchers wanted to test what would happen if a pig developed a bowel blockage. Since they were low on funds, all they had was a cork, some safety glasses, and a trained monkey. For weeks, the trained the monkey to remove the cork from the pig, so the researchers could study the reaction. Then, the fed and fed and fed the pig. It ballooned into a giant, pink hog.
The day arrived to pull the cork, and the monkey scampered of to do his job. A few seconds later, and there was a giant explosion and crap flying everywhere. When the emergency crews got the the site, the found the two researchers sitting in pig stink laughing as loud as they could. One rescue staff was told what happend, then asked, "What is so funny about that?" A researcher replied, "Oh, the funny part was watching the monkey try to put the cork back in!"
