This month’s edition of Trampoline Hall—the monthly Toronto lecture series in which the speakers are required not to be professionals in their topic—features David Dineen Porter on modern North American dialects, Kalpna Patel on spelling bees, and Freddie Rivas on living “on the dole.” There will also be a special performance by curator Becky Johnson’s improv duo (with Kayla Lorette), the Sufferettes, who have recently begun a summer-long “tour of Toronto.” As always, the evening will be hosted by Misha Glouberman; the doors will open at 7:40 p.m. (and close at 8 p.m., when the lectures begin). A very limited number of tickets will be available at the door, starting at 6:30 p.m.
