Brian's final response is a common one amongst speech-language pathologists who are suffering from relational difficulties. Nonetheless, to minimize frustration, I would have done things a little differently. Instead of having Stewie say, "whip," he should have started with the compound component, "cool." Then worked on the /l/. The omission is clear... but why is the /h/ being over-emphasized?
