Those who have seen brentalfloss live know that he likes to get the audience involved whenever he can. A popular part of his act is when he plays a game of "Mad Libs" with the crowd, inserts their responses into a popular song, then sings it. The result is always juvenile, but that's the only true way to do a "Mad Lib"!
During this year's A&G Ohio convention, Brent tried something new by tasking the audience to come up with complete lyrics for a videogame tune, the song of choice being Snake Man's theme from Mega Man 3. It didn't turn out that bad, considering it's a patchwork of input from various folks.
The activity sounds like it was a blast, and I hope Brent does it more often in future shows!
