51 Days - Just 51 Days

Four village board officials walk into a local bar; they're laughing and appear to be in a jovial mood.  They sit down at a table and one asks, "Bartender can you bring us a round of beers please?"  It's obvious they're excited about something as they are all smiling and just having a gay old time. 

When the bartender brings their beer over, they stand up, raise their glasses, and propose a toast - "51 days! 51 days! Just 51 days!"  Soon they order a second round and this time they all jump up and do a happy dance around the table, exchanging high-fives while still chanting, "51 days, 51 days, 51 days." 
The bartender is dying of  curiosity and asks, "What's all the excitement about boys?"  

One of them points to a beautifully framed child's picture puzzle of Ronald McDonald - completely put together - laying in the middle of the table.  "There ... can you see it?" they ask with excitement. 

 
The bartender stares at the small puzzle of Ronald McDonald laying in the center of the table. "Well do you see it?" asks one of the village officers.

"Well I must be slow today," says the bartender, "can you boys help me out; I don't get it?" 

"Well, many people in this village think our village board is run by a bunch of idiots so we decided to set the record straight. Last month, the four of us got together and bought this puzzle of Ronald McDonald over at Wal-Mart.  Together, we worked as a team a few hours each night and today we finished putting this puzzle together. The label on the side of the box said 2-4 years, but we were able to put it together in just 51 days!"
