When you sign on to make a movie starring Vine and YouTube pranksters Marcus Johns and Cameron Dallas, you have to expect that behind-the-scenes tomfoolery might be at an all-time high. Hopefully the producers of "Expelled" knew this, since Johns himself told MTV News that bicycle theft and sugar binging were some of the highlights of his filming experience.

"We had this tandem bike that we just drove around this neighborhood when we weren't filming," Johns, who plays Dallas' older brother in the film, said. "We went to a Ralph's and went up and down the aisles, and we got kicked out. It was a bonding moment, because we felt like we were kind of becoming our characters, getting into shenanigans with each other, but just in real life."

Johns added that another offscreen bonding moment with Dallas happened over one of life's greatest equalizers -- baked goods.

"[During] our first really big, long scene at night... I had to eat a bunch of cupcakes," he said. "We were just laughing, I was impersonating our dad in the movie. I was wearing a mustache... It was just a crazy night, but it was fun, there were a lot of laughs. Just goofing around and eating a thousand cupcakes was a fun night with Cam.... I legitimately probably consumed at least six full cupcakes."

"Expelled is playing in select cities now, and will be available for purchase on iTunes/On Demand/Digital HD platforms on December 16.
