Jimmy Fallon recently sent a writer out to show that either no one knows how to pronounce La Croix, or no one listens to writers from the Jimmy Fallon show. The set up was simple: the writer hit the streets of New York and purposely mispronounced La Croix while talking about the product. Not one person corrected him.
Some examples of the absurd pronunciations: La Chhhhhhx, Le Quaff, L.A. Croy and La Croy-voy-voy. In case you're wondering, according to the company it's pronounced la CROY.
