Mr. Phone: "Yeah, I see Dr. Nerve for my headaches, and when I had one last month he called in some Migroblast, and it was really effective. Do you know if he'll call it in next time I have a headache?"
Dr. Grumpy: "Are you having a headache, sir?"
Mr. Phone: "No, I'm fine, I haven't had one since then. I only get a few each year. But if I have one, will he call in the Migroblast again?"
Dr. Grumpy: "Why don't you call his office on Monday and ask?"
Mr. Phone: "Oh, I guess I can do that. Hey, have a good night!"
