At a local bar, a large group of blond women came in, obviously celebrating. As they entered, they were chanting, "51 days, 51 days, 51 days!" They ordered several rounds of drinks, chanting all the while.
Finally, the bartender got curious, and asked what they were celebrating.
"Well, we bought this jigsaw puzzle, and it said on the box, "2 to 4 years", but we finished it in only 51 days!"
