Theatre Passe Muraille presents Go Chicken Go’s production of [boxhead], by Darren O’Donnell. The show is a surreal comedy where science and the nature of existence clash. A geneticist wakes up one morning to find a box secured to his head. Distraught when he remembers that it’s his birthday, he accidentally clones himself, but the results splinter reality and awaken the gods. Chris Abraham directs.
