After Cecilia's glorious yet unconventional arrival into the world, it's time for the Dunder Mifflin staff to resume their roles as Pennsylvania's most outrageous office staff.

This week's episode (the office)begins with Michael acknowledging St. Patrick's Day in a full Irish brogue, as Kelly and Ryan engage in their usual bickering. Michael explains how this happens to be a very popular holiday in the Scranton area, as this is "the closest the Irish will ever get to Christmas."

Jim makes his much-anticipated entrance back into the office after the birth of his daughter, and finds that things have not changed a bit — except that Dwight has connected their workstations in order to make himself a "mega-desk." Unhappy with this threat to his dominion, Dwight snarks, "Tweetle Dee and Tweetle Dumbass are back. All I care about now is mega-desk, getting more mega-desk."

Jo, Dunder Mifflin's new resident CEO from Sabre, is still happy to spend time in the Scranton office, mostly because her dog loves "peeing in the Scranton snow." In order to get more attention, Michael brings her a special gift, which happens to be a box of coal. Jo doesn't quite get it until she is informed that coal powers all of the buildings in the area. In return, she promises that if Michael ever wants to travel to Tallahassee (her "neck of the woods") he always has a place to stay — an idea that clearly excites him.

Andy and Erin both seem to be excited for their upcoming first date, and Andy compares the feeling and night to a How I Met Your Mother episode, explaining how "it is the night that your kids will be waiting to hear about. You better have a good story to tell them."

Dwight wants five more minutes with the "mega-desk," but Jim does not agree. Dwight explains how "they say that no man is an island. False. I am an island and it is volcanic, and it will erupt with the molten hot lava of strategy." He begins to harass and use a sarcastic tone with Jim in hopes of convincing him to go home and be with his daughter and Pam. As usual, he is unsuccessful.

As things continue, Erin is becoming sick, but in order to keep her date with Andy from being cancelled, she tells Jo that she is fine, doesn't need to go home, and never has health problems — "except for the time I was in the hospital from age three until six."...

Until next week America, your homework is this: learn the Irish Jig. You may never use it, but if you do — we can't afford another Meredith and Kevin situation.
