Funny blonde joke (not poem)

Two blondes walk into a bar with a cookie monster puzzle and order drinks. A few more walk in and they all cheer 'yay 24 days!' over the next hour or so, m ore blondes walk in and they all cheer 'whoo, 24 days!' finally two more walk in and go to the bar, again cheering. the bartender asks 'what's with the 23 days thing?' the closer one says 'on the box it said 2-5 years, and we completed it in 24 days!'
