A man walked into his usual watering hole, ordered a beer and sat at the bar. He noted there were three blonde ladies at a table doing tequila shots. Before each shots they would clink their glasses in a toast and shout "twenty seven days!". His curiosity got the better of him, so he sauntered to their table and asked what they were celebrating. "Oh" one of them replied, "we are celebrating our intelligence". Now he was really curious. "What do you mean? Did you pass the bar exam, or maybe graduate from medical school?" "Oh, nothing like that" one of the blondes replied. "We just did a jigsaw puzzle, and it only took us twenty seven days! And, on the box it said 3 - 5 Years!".
