People that work the late-night shift at a fast-food drive-thru probably think they've seen just about everything. But I doubt they've ever encountered anything quite like this.

An extremely talented acappella group decided to spread some Christmas cheer to a group of workers. But they didn't just roll down the windows and sing a couple of carols. They went all out by pulling along a trailer complete with a living room set for full effect.

What's even better than the group's spot on singing was the reaction by the drive-thru crew. They all had "Super Sized" smiles, from ear-to-ear.
