Dallas' comedy scene has grown so large and expanded so much that it's really hard to come up with a way to make a stand-up show stand out now that almost every theater, club and coffeehouse has an open mic. The only place left to hold an original, one-of-a-kind comedy showcase is to do one on a public street, and comedian Gretchen Young, aka GretchYo, found a way to do that without getting an angry letter from the North Texas Transit Authority. Young created the rolling comedy roadshow Destination Unknown, in which the audience sits on a bus and watches a series of Dallas' best up-and-coming stand-ups such as Tony Casillas, Ashley Elias and herself do a tight 15 minutes of some of their A-list material while the vehicle's in motion. The bus has a list of destinations to local bars and breweries that the guests don't know about until it comes to a stop. Something like this could reinvent the comedy-club concept with its faux brick wall, stool and two-item minimum with an overpriced ticket.
