While shopping for Listerine recently, I was surprised to see a limited edition variety of it combining two unlikely flavors, coconut and lime. For a moment, I considered buying it. Then, I thought, "If this were a soda, juice, or a type of chocolate in a sampler, would I buy it? Maybe once, out of curiosity. But mouthwash?"
I like lime flavoring, within reason; in fact, I think ginger lime is the best of the Diet Coke flavors introduced three years ago. Combined with coconut, though? I can tolerate coconut flavoring once in a while, but I don't seek it out.
I reverted to a less daring mint flavor of Listerine. My sense of adventure has its limits.
