ComedySportz features hilarious all-ages friendly improv-comedy and has been a Chicago favorite for 25 years. And, to celebrate "25 yearz", ComedySportz is Giving Back $5 off every full-price individual ticket to a worthy charity. For 9/27-9/29, that charity is Sam Thompson Foundation. Sam, the brother of ensemble member Zach Thompson, passed away this year after 31 years of battling cystic fibrosis and other serious illnesses. ComedySportz's donation will help his family defray Sam's extensive medical expenses.
