Zmackburgers: Every Thursday evening until May 30, local comedy troupe, the Zmackers will be performing a free show! And if their jokes aren’t enough to make you “split your sides,” the peanut butter and bacon cheeseburger (the “Zmackburger”) they’ll be serving, certainly will. If that’s not enough, you’ll also have a chance to win a copy of the Chinese book Improv Wisdom.
