Senior Citizen Flash Mob Performing ‘Last Christmas’ Is Sweeter Than Gingerbread

Short on holiday spirit? Then this video, which shows a senior citizen flash mob performing 'Last Christmas' from 'Glee,' will surely get you in the mood.

The seniors spontaneously belt out the tune while at a Target in Kansas. One of them even does so while using a walker.

Admittedly, their timing is way, way off, but this doesn't diminish their joyful performance in any way.

Watch the senior flash mob celebrate the holidays below.
