One night there are 10 blondes celebrating at a bar. They are all really drunk. Every few minutes they all yell "Fifty-one!! Fifty-one!!" then clink their glasses and knock back another drink.
The bartender is curious but decides not to ask because they are drunk. Well they keep yelling it again and again and again. Eventually the bartender gets really frustrated because they've broken 10 glasses and other patrons are becoming annoyed at all the noise.
He goes over to ask them what's going on. One of the blondes holds up a Barney jig-saw puzzle and says,
"Well everyone thinks that we are dumb blondes, so we proved everyone wrong." she explains "On the box it says 2-4 years and we finished it in 51 days!"
