Strongly inspired by the show "Whose Line Is It Anyway", the show "Improvável" (Improbable) is a humor project based on improvisational games in which the audience has fundamental importance for creating the scenes. In it, a Master of Ceremonies guest explains the improvisational games, gives the challenges to the actors and selects the suggestions of the audience. Besides the master of ceremonies, the Barbixas also receive a guest actor who will play with them. Since everything is based on improvisation, the audience will always see a different and interactive play. "Improvável" began with monthly performances in 2008. Some of the presentations are recorded to feed the Improvable webseries available on the Barbixas channel on Youtube.
