If you are wondering what a Goober is, there is a picture of one at:
An ice cream store employee is standing behind the counter on a typical day, when the door bursts open and in come four exuberant goobers. They come up to the counter, order 10 triple-scoop cones and take their order over and sit down at a large table. Then they begin chanting, "51 days, 51 days, 51 days!"
Soon, three more goobers arrive, take up their cones and the chanting grows. "51 days, 51 days, 51 days!" Two more goobers show up and soon their voices are joined in raising the roof. "51 days, 51 days, 51 days!"
Finally, the tenth goober comes in with a picture under her arm. She walks over to the table, sets the picture in the middle and the table erupts. Up jump the others, they begin dancing around the table, exchanging high-fives, all the while chanting "51 days, 51 days, 51 days!"
When the frenzy dies down a little bit, the employee asks one of the goobers, "What's all the chanting and celebration about?"
The goober who brought in the picture pipes in, "Everyone thinks that goobers are dumb and they make fun of us. So, we decided to set the record straight. Ten of us got together, bought that puzzle and put it together. The side of the box said 2-4 years, but we put it together in 51 days!"
