Plot. Liz, expressing a general disdain for the Irish, plans to spend St. Patrick's Day in her apartment with boyfriend Criss ridiculing the revelers outside. Criss slips "I love you" into their conversation, but Liz changes the subject. Ex-boyfriend Dennis Duffy shows up injured at her door, in what she presumes is a ploy to win her back. Criss is hospitable to Dennis, who claims to now be married. After Liz claims her love for Dennis in effort to  call his bluff, Criss storms out angry over her ease with saying that. Liz finds out that Dennis's wife does in fact exist, and Dennis points out that Liz has been mistreating Criss. She finds Criss on the street serving hot dog buns to customers and finally professes her love for him. Jenna and Tracy once more are hosting coverage the St. Patrick's Day parade. New page Hazel starts a fight between them by inadvertently giving a cue that Jenna is a bigger star, also angering Pete. She tries to fix it by replacing their names in the  script with "Host #1" and "Host #2", causing both to read the lines for Host #1. Kenneth, at home on a Saturday thanks to his new job, resists the urge to intervene when he sees the disaster on television. Both stars are replaced by Al Roker in mid-broadcast and leave the set. When the car waiting for one of them is labeled "Host #2," they are confused about who should get in, and confess the underlying emotions that are driving the fight. They return to host the rest of the broadcast. Hazel discovers that Kenneth made the sign and  drove the car to force this resolution. Jack discovers that the writers are playing a fantasy boardgame in the office because their faces are too punchable on St. Patrick's Day. He gets wrapped up in the economic dynamics of the game, but ends up losing most of his assets and finds it to be metaphor for his stagnant career at Kabletown. After some soul searching at St. Patrick's Cathedral, he comes up with a tactic to win the game, and returns to general adulation.
