Seventeen Days!

A man walks into a bar and notices three blonds giving each other high-fives, clicking their glasses together, and chanting, "Seventeen Days! Seventeen Days! Seventeen Days!" Unable to overcome his cursiosity, the fellow approached the table and inquired about the cause for their celebration. "Well," replied the blondest of the three, "we just finished a jigsaw puzzle in only seventeen days."

"So, what?" asked the fellow, obviously unimpressed.

"Well," she replied proudly, " It says '4-6 years' right on the box."
