Your Friday Flash Mob, Courtesy of Arby’s

We’ve seen the (sorta) good, bad and downright turrrrible when it comes to flash mobs, but since yours truly is under the weather, I could use some pep without being forced to watch Glee. We’re not sure which category this falls under, but guess this Arby’s karaoke singalong will have to do for now. A storm couldn’t dissuade this 125-strong crowd to wax Gene Kelly and chime in with their version of Arby’s new digital ad, which carries the tag, “It’s Good Mood Food.” The 50-year-old brand’s SVP, advertising and marketing communications, Bob Kraut says, “We wanted to inspire good moods and give people a chance to stop in the middle of their hectic day and have some fun.”
