Pub crawls are basically walkathons that allow drinking. You start in one bar. You drink a bunch of drinks. You walk to another bar. You drink more. You walk to another bar. Repeat the process until you run out of bars or kiss the pavement. Pub crawls could use more pizzazz. The folks at the local animated comedy powerhouse known as Cyanide & Happiness have taken the concept of a simple pub crawl to an insane new level with their annual Banana Bar Crawl, now in its seventh year. It’s quite simple. To participate, you must “be a banana,” according to the guidelines on their Facebook event page. That can mean wearing a banana costume, dressing in the same color as a banana or entering a metaphysical state where your mind’s eye makes you believe that human life has been replaced by bananas. You also have to be at least 21 years old. All you have to do is show up at Braindead Brewing at 2625 Main St. in Deep Ellum at 8:30 p.m. on Saturday, March 25 and starting following the banana collective as they go from bar to bar. This event is free and open to the public who can legally drink. Visit www.facebook.com/explosm for more information.
