Honolulu's Improv Superette comedy troupe is opening its third season on a high note, with the opener selling out in four minutes — good news for the group and for local comedy fans, though a squeeze for anyone who missed a ticket.

• The group runs monthly improv shows in Honolulu built around local humor and growing up in Hawaii.
• Demand is climbing fast: the season-one opener took three hours to sell out, this one took four minutes.
• Shows run about two and a half hours, mixing short "Whose Line Is It Anyway"-style games with longer 15-minute story scenes.
• The troupe formed two and a half years ago when a group of longtime performer friends decided to work together.
• Full show clips get posted to Instagram and YouTube for people who miss out on tickets.

Outlook: The season schedule runs through next summer, and the group is looking for bigger venues and adding corporate team-building workshops to meet the growing demand.
