Dan and Mary have an only daughter, Norah, who is working as a stenographer for the firm of Weinersteiner & Co. She is engaged to be married to Terry O’Roarke, a motorman on the street cars, when Weinersteiner meets her and falls in love with her. He wants to see Norah home, but she declines. He follows her out and sees that she is met by Terry. The Dutchman gets angry and goes to his register to find out where Norah lives. He arrives at Norah’s house while Dan has gone out for a “growler” of beer, Norah’s mother thinks that something has gone wrong at the office when Weinersteiner makes himself known to her. He soon reassures her and makes himself at home. Dan returns with the beer and tries to hide the can when he sees the fat Dutchman. His wife tells him who he is. Then the Dutchman makes himself solid with Dan by giving him cigars, etc. Very soon Dan and the Dutchman are on good terms and he bides with the Dutchman for Norah’s hand, while the mother is very indignant, and takes the side of Terry, who is forbidden by Dan to come any more to the house. Thus matters stand until St. Patrick’s Day. The family are all dressed up in their best when Terry comes in, and as it is St. Patrick’s Day, Dan has to shake hands with him. The mail arrives with a box of Shamrocks from Ireland. Dan opens the box and they are all deeply affected when they see it and each take a spray and kiss it reverently. The Dutchman enters and greets each effusively. Then he spots the Shamrock, and to the horror of the others, he puts pepper and salt on it and eats it. Dan, Terry, the mother and Norah throw him out of the window.
