Four Day Weekend: Three members of the Dallas-based comedy sextet known as Four Day Weekend have experiences in common – studies at Chicago’s prestigious comedy mecca Second City, and stints with Ad-Libs, Dallas’ long-standing improv troupe. Beyond that, all six members of this new improvisational company have a common goal – to keep the laugh meter past 10 with material gleaned from audience suggestions. Improv is one of the scariest exercises an actor can perform, but daredevils Four Day Weekend crave danger the way most of us crave Kool-Aid with our baloney sandwiches. Four Day Weekend performances happen Friday, 10 p.m. and Saturday, 11 p.m. through March 29 at Casa Manana Theater on the Square, 109 E. 3rd St. at Main, Fort Worth. Tickets are $9.
