The American version of The Office remains a pop-culture phenomenon, despite going off the air in 2013. The everyday heroes of the Dunder Mifflin Paper Company are celebrated at Scrantonicity, an Office-themed party that takes place from 8 to 11:30 p.m. Thursday, December 12, at the Ready Room (4195 Manchester Avenue; www.thereadyroom.com). There will be Office trivia, cocktails inspired by the show, a costume contest and recreations of the Dunder Mifflin Olympiad and the Dundee Awards. Tickets are $15 to $37, and a portion of the price benefits Life for Life Gym, North Side Community School and Mission: St. Louis.
