In need of a new earworm that will have you humming away the rest of the day, even if you ultimately forget where it came from? Well, watching this vintage commercial from Taco Bell will accomplish just that!

In this Taco Bell TV ad from 1979, you can see some of the great staples they've always had, some menu items that have come and gone, their old tag line, and of course a bunch of smiling people who are happy to be eating food that's made fresh.

Now turn up the volume and get ready to sing "Taco Taco Taco Bell" for the rest of the day!
