Never knew romance can turn sour so quickly

Dexter is actually wrong. Its omelette au fromage not du fromage

It was Dexter Laboratory who made me want to look up how to say it and from there I learned more.

I'm French. "Omelette du fromage" is actually totally correct, if you mean that the omelette belongs to the cheese. Cheeses have a high status in French society, I wouldn't be surprised if some owned omelettes.

Good point. The cheese totally could own the omelette.
