Two blondes walk into a bar smiling and talking excitedly, each 
 orders a drink. 
 
 They go and sit down and start toasting and cheering, "51 days!! 
 51 Days!!" 
 
 About five minutes later, another blonde walks in, orders a drink, 
 and joins the other two in the cheering and the toasting. 
 
 Finally, another blonde walks in with what looks like a large 
 cardboard picture. She puts the picture thing in the middle of the 
 table, grabs a drink from the bar and then sits at the table and 
 starts cheering with the others, "51 days!! 51 days!! 
 
 The bar tender curiousity aroused, walks over to discover that the 
 picture is a Cookie Monster jigsaw puzzle. Bemused he turns to one 
 of the blondes who is by now quite red in the face from all the 
 whooping and cheering and asks, "What on earth are you doing??" 
 
 "Well," the blonde says, "everyone thinks blondes are so stupid, 
 so we proved them wrong. On the box this puzzle came in, it says 
 2-4 years, but we finished it in only 51 days!!!
