Every Monday night among the old dusty couches of the Maintenance Shop’s Green Room, members of a local comedy group meet to put their mojo into overdrive.

The 11 members of Grandma Mojo’s Moonshine Revival show up randomly in ones and twos, and there is no way to tell when the meeting — which bears more resemblance to a loose gathering of good friends — officially starts.

Printouts of rough sketches exchange hands, and most of the hour is spent in laughter. The scripts are loosely titled with names like “The Baby One” and the “Evil Justin Saga.” This may seem confusing, but it’s how the improvisation-infused group operates.

Dathan Brown, freshman in pre-journalism and mass communication, who joined the group last fall, says people are often confused when he tells them he’s in something called Grandma Mojo’s, and often describes it as a mix between “Saturday Night Live” and “Whose Line is it Anyway?” — except better.

There is no real structure to Grandma Mojo’s creative flow. From stories about friends and random comments on world and local events, skits and ideas begin to take shape.

“A lot of our good ideas happen because we start talking about something somebody thinks is funny. We don’t really practice skits until the day of the show,” Brown says. “If something is popular or liked, we’ll bring it back. Seems like no one really likes the [Department of Public Safety], so we make fun of them a lot.”

Cole England, senior in animal science, has been in Grandma Mojo’s for four years. He says he feels the group has evolved since he began performing with the troupe.

“When I started this, we used to not do the improv in the middle,” England says.

“Last year, we started putting more of the improv games in. We found that we needed to do a better mix of improv and sketch comedy, because the more improv we did the worse the shows got, and when we tried to cut out the improv games people started getting mad. I think now we’ve got a nice mix in there.”

Even with the mix, improvisation remains an essential part of the show. Even the sketches members write are not finalized until the moment they are performed, and their only rehearsals are on show nights.

“We have a vague idea of what the sketch is supposed to be about and we improv our way through it,” England says.

The group, formerly known as the Mighty Monkey Power Hour, got its unique name from last-minute inspiration.

When its first performance came around, it was still nameless. England says one impatient member said, “Let’s just call ourselves Grandma Mojo’s Moonshine Revival and get out there!” and the group has stuck with it ever since.
