If you've ever dreamed of being in the Guinness Book of World Records, now's your chance. Tonight, the Goodman Theatre, in partnership with the Chicago Outdoor Film Festival's showing of the Marx Brothers' "Duck Soup," will attempt to set the record for "most people wearing Groucho Marx glasses" at the same time. Arrive at Butler Field in Grant Park between 6-7 p.m. and sign in near the screen to get your free glasses. In order to be considered for the book, everyone will have to wear the glasses for at least 10 minutes and pose for photos and video (around 8:15 p.m.).

...or you could just come for the movie, which begins at 8:52 p.m. (sunset).
