I am seeing a nice blonde girl at the moment and she didn't like this at all. So I thought I'd share ;
Five blonde women enter a bar and order a bottle of champagne and ten glasses from the bartender. They go and occupy a table, set a small framed picture in the middle, and start "high fiving" and dancing around the table chanting, "51 days! 51 days!".
A few minutes later, five more blondes enter the bar and join the others at the table. There is much laughing and merriment, alternating with the ritual chanting of, "51 days! 51 days!".
Finally, the bartender can no longer control his curiosity and he strolls over to the table to see what is going on.
In the center is a picture of the cookie monster in a frame. When the bartender asks what the celebration is all about, one of the women says, "We were all tired of the blonde jokes about how dumb we are, so we got together and put this puzzle together. On the package it said '2 to 4 years', but we all worked together and put the puzzle together in 51 days!"
