The six-headed hydra of spontaneous comedy known as Four Day Weekend has been wreaking havoc on North Texas doldrums since 1997. Critically adored by the metroplex’s most prominent presses, the group squelches laughter droughts with their weekend bouts of unscripted hilarity. The professional troupe of cut-ups, many with film and Second City Conservatory of Chicago credentials, happily share the tricks of the trade in their four-level training center. Emphasizing “truth in comedy,” the curriculum covers fundamentals such as characterization and long-form improv, giving students the tools they need to extract their inner hilarity or survive an hour in a prop closet with Greg Proops.
