...WHAT A TWIST.

A mysterious mustached guy tries to blend into a flash mob event during the spirit week at College of DuPage in Glen Ellyn, IL.

For this year's Black Friday, the folks over at Improv Everywhere staged a huge line in front of a dollar store.

Let's face it: In the same way we all have a zombie plan, our instincts are movie-honed for a secret-agent scenario -- as soon as these guys are given a destination and a countdown clock, the inner Bond comes out just as the train station turns into an obstacle course.

One of the coolest marketing stunts ever.

Sometimes, on quiet afternoons at Twitter HQ, a guy in a letterman jacket will start a flash mob.

Watch as tech geeks the lunchroom over rise up to join him in a choreographed dance to Justin Bieber's "Baby."

All it took was a brass band and a flash mob dancing to Michael Jackson's "The Way You Make Me Feel."

Marketing Campaign of the Day: Budweiser Canada surprises two recreational league hockey teams from Port Credit, Ontario, with professional-league-grade theatrics, including a flock of fans, play-by-play commentary, and other accouterments of a professional game.

Sure, it's (still) nothing new -- but it'll warm your cold, cold heart just the same.
