This ad comes from Krystal fast food restaurant in the United States and premiered during the Super Bowl. The commercial is for Krystal’s new bacon cheeseburger. While bacon cheeseburgers aren’t anything new, these particular ones are more like sliders and double as an engagement ring box—at least, in this commercial they do.
The romantic scene starts with a man opening up the bun (which looks like an engagement ring box) in front of his girlfriend. Overwhelmed, she accepts and they start telling people walking by.
The entire commercial is meant as a parody of a romantic proposal scene. However, for this couple the combination of cheese and bacon is too much to resist. Whoever said diamonds are a girl’s best friend must have never been served a Krystal’s bacon cheeseburger before.
