a group of blondes went into a bar and they were chanting '48 days, 48 days' and they were holding up a cookie monster puzzle. another group of blondes came into the bar and they were chanting the same thing. the leader of the group stood on a chair and said 'we blondes have been thought of as stupid but we aren't'. the bartender asks one of the blondes 'what is all the cheering about?' and the blonde replies 'the box on the puzzle says 3-5 years but we completed it in 48 days!'.
