Mr. Ictal: "I didn't take it on Saturday."
Dr. Grumpy: "Why did you stop?"
Mr. Ictal: "Because you told me to!"
Dr. Grumpy: "What?... I don't have anything like that in your notes."
Mr. Ictal: "At our last visit you reminded me not to drink excessively on Noseizure! So, since my buddies were all in town, and I knew we were going to get wasted on Saturday night, I stopped taking it for the day."
